What does unprotected connection mean in Mozilence. Firefox error correction "Your connection is not protected. Disable SSL checking

When you establish a secure connection to the HTTPS server, the Mozilla Firefox browser instead of the expected web page can display a warning "This connection is untrusted." How to react to it: to remove the ban, find out what reason it is displayed, or is it better to leave the site?

The selection of the solution depends on the type of identification error, system settings, the "bottom fee" site. These factors help to prevent personal data leakage and viral attack. Or, on the contrary, save from unnecessary suspicions (when a computer, in fact, no one threatens anything, and only the options are required).

How to prohibit or enable promptly?

If in the process of the web surfing the message "Unclusive connection" will appear when you try to go to an unfamiliar (or doubtful) site, immediately activate the lock:

on the Messages tab, click the "Leave from here!".

And if you are 100% sure that your computer is not infected with the viruses and the site to which you want to get is safe, you can enable the connection in the same tab:

1. Open the spoiler "I understand the risk."

2. Click on the "Add to Exception" button.

3. In the Advanced window, click the "Certificate" button (located near the address of the locked website).

4. Turn on the add-on "constantly store this exception" (click the mouse click the checkbox).

5. Clazzize "Confirm the exception ..." (button at the bottom of the window).

Analysis of identification errors and their elimination

To find out the error code, on the Warning tab, click "Technical Details" and read the information in the last line of the Error Code spoiler.

Attention! The code analysis allows you to prevent the appearance of an error in the future. Neutralize the reason for its occurrence.

Consider the most common cases of incorrect identification:

Certificate is expired or not valid

These problems are referred to as Firefox, respectively, as SEC Error Expired Certificate and SEC Error Expired Issuer Certificate. Quite often, the cause of their occurrence is the wrong date and time set in the clock of the computer.

Check and adjust the clock and calendar if necessary:

1. Clause the left mouse button by date in the tray (in the lower right corner of the display).

2. Open the "Changing Settings".

3. Click the Edit ... button.

4. In the additional window, set the number, month, year. Clazzo "OK".

5. In the Date and Time panel, also click "Apply" and "OK" to activate the changes made.

The certificate is valid only for a specific site.

(SSL Error Bad CERT DOMAIN)
This error appears in cases where the server sends another site to the browser. In other words, fake sends.

However, situations are known when Firefox blocks similarly trusted resources. This is due to the fact that the certificate applies to a specific part of the website. For example, for the address in the "https: // www format. . Ru "It acts, but for" https: //. RU "(without www) - no longer.

Unknown Publisher Certificate

(SEC Error Unknown Issuer)
Famous certificates can be detected by Firefox as unknowns due to damage to CERT8.DB (identifier storage). Remove it in the profile and try again to install a secure connection:

1. In the upper right corner of the browser, click on the "Three Strips" icon.

2. At the bottom of the tiled menu, click the "Question Sign" icon.

3. To the submenu, select "Information to solve problems".

4. On the Application Information tab, in the Column "Profile Folder", click the "Show folder" function.

5. In the window that opens, in the browser directory (in the Profile folder), delete the Windows file CERT8.db by the Windows file:

• candle on it right-click;
• in the opened panel, click "Delete".

Also access to the identifier database can be obtained without opening the browser:

1. Click on the "Start" icon.

2. In the "Search" line, specify the path to the folder with the profiles:

% APPDATA% \\ Mozilla \\ Firefox \\ PROFILES \\

3. In the window that appears, go to the folder with the profile of the current account, and then remove CERT8.DB in it.

Browser got a weak ephemeral key

(SSL Error Weak Server Ephemeral DH Key)
This access blocking may arise due to conflicts with the version of the SSL 3.0 protocol. To disable its support, follow these steps:

1. In the new tab, in the address bar, type - about: config.

2. Under the text of the warning, click "I promise I will ...".

3. In the "Search" line, dial - SSL3.

4. Click right back on the first configuration list - Security.ssl3.dhe_rsa_aes_128_sha.

5. Click "Switch" to the submenu. (The value will change with "True" to "false").

6. In the same way, disconnect the second in the list "... AES_256_SHA" list.

7. Restart the browser and try again to establish a secure connection to the locked web resource.

Comfortable and safe to you web surfing in Firefox browser!

It is considered the most stable browser who lacks the stars from the sky, but at the same time qualitatively performs its work. Unfortunately, periodically users of Firefox can face different kinds of problems. In particular, today it will be about the error "Your connection is not protected."

Ways to remove the message "Your connection is not protected" in Mozilla Firefox

Message "Your connection is not protected"The appearing when trying to go to the web resource means that you attempted to transition to a secure connection, but Mozilla Firefox failed to check the certificates for the requested site.

As a result, the browser cannot provide guarantees that the Opened Page is safe, in connection with which blocks the transition to the requested site, displaying an unnecessary message.

Method 1: Setting the date and time

If the problem with the message "Your connection is not protected" is relevant immediately for several web resources, then the first thing you need to do is check the correctness of the dates and time on the computer.

Windows 10.

Windows 7.

After the settings performed, try to open any page in Fairefoks.

Method 2: Setting the operation of antivirus

Some anti-virus programs that provide security on the Internet have an activated SSL scanning function, which can also provoke the appearance of the message "Your connection is not protected" in Firefox.

To see if antivirus or other protective program, the cause of this problem is, suspend its work, and then try to update the page in the browser and the error has disappeared or not.

If the error disappeared, then the problem is indeed an antivirus. In this case, you just have to disable the option in an antivirus that is responsible for scanning SSL.

Setting up Avast.

1. Open the Anti-Virus menu and go to the section "Settings".
2. Open section "Active Protection" And around the point "Web Shield" Click on the button "Tune".
3. Remove the checkbox from the point "Enable HTTPS scan"And then save the changes.

Setting up Kaspersky Anti-Virus

1. Open the Kaspersky Anti-Virus menu and go to the section "Settings".
2. Click on the tab "Additional"and then go to the sample "Net".
3. Opening the section "Scan encrypted connections"you will need to put a tick around the item "Do not scan protected connections"After which you can save the settings.

For other antivirus products, the procedure for disabling the scanning of the secure connection can be found on the manufacturer's website in the help section.

Visual video example

Method 3: System Scanning

Quite often, the message "Your connection is not protected" may occur due to the action of viral software on your computer.

In this case, you will need to run a deep-scanning mode on your computer for viruses. You can do it like using your antivirus and a special scanning utility, such as Dr.Web Cureit.

If viruses will be detected by scanning results, cure them or delete, after which you will definitely restart the computer.

Method 4: Deleting Certificate Storage

On the computer in the Firefox profile folder all information about the use of the browser, including certificates data is stored. It can be assumed that the certificate storage was damaged, in connection with which we will try to remove it.

From now on, you can start Firefox again. The browser will automatically create a new copy of the CERT8.DB file, and if the problem has consisted in a damaged certificate store, it will be solved.

Method 5: Operating System Update

The certificate verification system is carried out by special services embedded in the Windows operating system. Such services are constantly being improved, and therefore, if you are not in time to install updates for OS, you may encounter Firefox with an error check of SSL certificates.

To check Windows for updates, open the menu on the computer "Control Panel"and then go to the section "Security and System" - "Windows Update Center".

If any updates are detected, they will immediately be displayed in the window that opens. You will need to install all updates, including optional.

Method 6: Incognito Mode

This method cannot be considered a way to eliminate the problem, but only a temporary solution. In this case, we offer to use a private mode that does not save information about search queries, history, cache, cookies and other data, and therefore this mode sometimes allows you to attend web resources that Firefox refuses to open.

To start incognito mode in Firefox, you will need to click on the browser menu button, and then open item "New Private Window".

Method 7: Turning off proxy

According to this method, we completely turn off the proxy function activity in Firefox, which can help solve the error we consider.

Method 8: Block Bypass

Finally, the final reason that manifests itself not on several secure sites, but only on one. She can say that there are no fresh certificates for the site that cannot guarantee the safety of the resource.

In this regard, you have two options: close the site, because It can carry a potential threat to you, or bypass blocking, but provided that you are absolutely confident of the site security.

Video lesson by solving this problem

Today we reviewed the main reasons and ways to eliminate the error "Your connection is not protected". Using these recommendations, you are guaranteed to eliminate the problem that occurred and you can continue the web surfing in the Mozilla Firefox browser.

The HTTPS protocol today is one of the basic protocols to exchange data on the Internet. It allows you to encrypt the transmitted information, provides protection against sniffer and other cyberacto, ensures the stability of the connection and confidentiality of the transmitted data. But how to be in a situation where the user wants to disable HTTPS? In this article, I will tell you how to turn off HTTPS in Yandex and Google Chrome browsers and on the website of the social network VKontakte.

Security primarily

So what is https? This name is the abbreviation from HyperText Transfer Protocol Secure (in the "Safe Hypertext Transfer Protocol"). And it is a symbiosis of several network protocols - basic HTTP and cryptographic SSL / TLS. Now the transmitted data is encrypted to improve the security of the installed Internet compound, contributing to its reliability and security.

Now, more and more sites are moving to the HTTPS connection as due to the increased security level of this protocol and due to the Google promise to provide priority to sites with HTTPS in the issuance of search results.

Turn off https

At the same time there are situations when you may need to disable HTTPS support in the Yandex, Chrome and Opera browser. This is due to the peculiarities of the work of some sites, not always working with the HTTPS protocol. Therefore, I will inform you how to disable HTTPS for specific sites on different browsers.

At the same time, I note that usually if you at least once go to any site by HTTPS, the browser will remember this domain, and next time you will perform an automatic redirect on the HTTPS version of this site.

How to disable https in the browser

To disable HTTPS in the browser for a particular site we do the following.

1. We leave this site, close all tabs, leaving one basic;
2. Clean the entire history of activity and cache;
3. We go to the browser's office page by Dr. in the address bar as follows:

In the DELETE DOMAIN entry field, you drive the name of the site domain (for example, sample.com), and click on "delete". Now the next time you enter the address of the site from HTTP, not HTTPS, and use the possibilities of an unprotected connection.

At the same time, consider the problems with the correct use of HTTPS protocol on your computer may be due to the dates or time incorrectly installed on it.

You can also change HTTPS security settings in your browser settings. For example, for chrome it can be done in the settings, select "Show Advanced Settings", and select "Configure Certificates" in HTTPS.

How to remove https from vkontakte

At the next entrance to the VK website, remember the features of the redirect (which is listed just on top), delete the reference to this domain as specified on top, and then go to this resource using HTTP.

If it does not help, you can try to enter this site from another browser.

In addition, I haveten to draw readers' attention to the fact that you should not hope for a site from HTTP using the reference where HTTPS is specified.

Conclusion

Using the HTTPS Protocol facilitates the protection of network connections and maintain the security of the transmitted data. In the same cases when the network resource works with HTTPS is unstable, you can disable the use of HTTPS with respect to this resource using the algorithm described above.

Greetings!
The Mozilla Firefox browser is for what to appreciate, let him and not the fastest, but at the same time the most flexible and functional. What is only worth a large number of extensions and additions, which was created for this browser.

And very saddened when problems arise in your favorite browser. Today we will consider a problem that is expressed in the message "Your connection is not protected" when you try to visit some sites.

Error "Your Connection is not protected", often occurs when you try to go to a resource that works through a protected connection (HTTPS). However, if the Firefox browser cannot verify the certificate that is required to create such a "protected connection" with the site, this message is inevitably.

In essence, the displayed message cannot be called an error in a classical understanding. It is rather a security measure that is notified by the user that there are problems that cannot provide adequacy (encryption) of the compound. As a result, the browser blocks the opening of the requested site.

In this material we will try to deal with the reasons for the occurrence of this problem, and we will make every effort to eradicate.

We remove the error in Mozilla Firefox "Your connection is not protected"

You must start with the first solution and progressively move forward until the error is eliminated.

Solution 1: Check the set date and time

This time must be brought first, namely the correctness of the installed date and time on the computer.

All certificates have a validity period: release date and end. And in the process of connecting to the site, the validity period of the certificate is reconciled with the date that is installed on the computer. If the time on the computer is defined correctly, the certificate will not be recognized as valid and the error will arise "Your connection is not protected".

If the date (day, month, year, time) is installed incorrectly, then it is necessary to establish the current value.

To do this, hover over the date that it is displayed in the right lower corner, and then click right key. In the displayed context menu, select Setting up dates and time.

A system window will be opened in which time setting is performed. Check if options are translated Set the time automatically, as well as Automatic clock zone setup In the included state.

If the options are not included, then use them. After a short period of time, the date and time is adjusted. If this happens, turn off these options and set the date and time value manually.

Solution 2: Anti-virus work

Modern antiviruses are not limited to only the scanning of local files, many of them now have Internet connection tools. And we are talking not only with a network screen (firewall), but also to control the traffic itself.

Control of protected SSL connections may well cause the message display "Your connection is not protected" in Mozilla Firefox.

In order to exclude this probability, suspend the protection of antivirus for time, after which try to go to the desired site again.

If the problem disappeared, it is quite obvious that the problem causes the antivirus, and in particular its control module of Internet connections / traffic. In this situation, it is recommended to update \\ reinstall the antivirus. If this does not help, you should write a letter to the Developer Support Service of your anti-virus solution.

In the meantime, you can disable the appropriate option in anti-virus software, which prevents access to sites that, in turn, operate on the connected encryption of the connection (SSL).

An encrypted connection scan option in Avast

In order to disable this option, open the anti-virus software menu, and then click on item. Settings.

In the displayed window, click on item Active defense, and then Web shield –> Tune.

And turn off the option Enable HTTPS scanningAfter removing the appropriate tick, and save the settings.

Option of scanning an encrypted connection in Kaspersky Anti-Virus

Call the menu in Kaspersky Anti-Virus, and after click on item Settings. As a result, a window will be displayed in which you need to proceed along the way. Additional-> Net.

There will be Scanning encrypted connectionsin which you will need to put a tick, which is responsible for disabling the eponymeal option. After that save the settings.

For other antivirus solutions, you can emphasize the appropriate guide to disconnect the control of protected \\ encrypted connections in the help or on the official website.

Solution 3: Check for viruses system

Various kinds of viruses and other malware are trying to embed as much as possible into the system. Some of them are trying to "wed up" in the network stack, so as can be intercepting / replacing traffic. These actions are quite natural can cause an error "Your connection is not protected".

Even if you are completely confident in the absence of malware on your PC, you still will not be superfluous to be sure about it again by checking the anti-virus system.

If you have an antivirus solution installed, refresh its base over the Internet and run full (deep) scanning. If you do not have antivirus, then you can use, for example, free and not requiring installation.

If the scanning results demonstrate the presence of malicious objects, then try to cure them (if there is such an opportunity for antivirus), or just delete. After that, it is mandatory to reboot.

Solution 4: Problem with Certificate Storage

During the Mozilla Firefox browser operation, the certificates used are saved in a special file, which is located in the profile folder of this browser. It is quite possible to assume that in the process of the browser, this file could be damaged. In this situation, you should try to delete it.

To do this, press the menu button (located in the upper right corner of the browser window), and then click on the icon reference and click on item Information to solve problems.

A window will be opened with technical information about the browser. Find it point in it Profile folder and click on the nearby button Open folder.

A file manager window will appear, in which the Firefox browser profile folder will be opened. Now close the browser itself, and then find and delete the file in this folder. cERT8.DB..

Now re-run the browser. Previously, the deleted file will be created again. Now you will only have to check whether the problem is solved. If the error window does not appear anymore, the problem was damaged by the certificate storage, which is located in the file cERT8.DB..

Solution 5: Install the latest updates to the operating system

In the process of creating a secure connection, the Firefox browser uses for this mechanisms that are available, including in the operating system itself.

If your operating system has not been updated for a long time, then the safety mechanisms have ceased to meet modern requirements. All this may well provoke an error of installing a protected connection (SSL).

The solution will be setting the latest updates for the operating system you use.

To do this, open the menu Startand find the application Windows Update Center.

After running it, a window will be displayed in which the current status of the system will be displayed.

For a compulsory start search start, press the corresponding button. At the end, install all the proposed updates (including optional).

Solution 6: Use of incognito regime

This option cannot be attributed to the method of complete elimination of the problem, but it will be quite conspicuous as a "temporary solution".

This browser operation mode is designed to increase user privacy. All that is entered in tabs that work in incognito mode does not preserve the browser itself in history. Those. If you were looking for something, attended any sites, then after closing this data (session cookies, cache, history of search queries, viewed pages, etc.) will be completely removed.

Working in this mode, the Firefox browser in some cases allows you to display sites that have problems with the installation of a reliable encrypted SSL connection.

To include mode Incognita And the opening of the corresponding tab must be pressed on the menu button, which is in the upper right corner, and in the displayed menu, select item Private window.

Solution 7: Disable proxy in browser settings

It may well be that on the occurrence of this error affects the activated proxy function in the Mozilla Firefox browser.

Let's try to disable it and see if the problem will disappear.

Turning off the proxy is carried out in the settings. To do this, click on the browser menu, select the item in the displayed menu. Settings.

The settings window will be opened. On the left there will be a menu, there click Additionally, and then on the right side click on item Net.

As a result, the appropriate settings block will be displayed. First point goes Compound. In it, click Tune…

Window will be displayed Connection parameters. It is necessary to switch to the item. Without proxy, and after clicking OK..

Decision 8: Bypassing the security system warning

So we came to the last reason that causes an SSL connection error, and it occurs on an opportunity of one single site, and the rest of the secure HTTPS compound open perfectly normal.

Most likely, the site itself has problems with the certificate (the validity period, canceled).

In this situation, the easiest way to refuse to view this site, however, if you basically need to see it, then you need to do the following:

In the error window, click on the button. Additionally.

An additional menu will be revealed, it will make it click on the button located there. Add an exception.

As a result, a warning window will be displayed in which it will be necessary to click Confirm the security exception.

Now the site should open without errors from the Mozilla Forefox browser security system.

Short outcome

In this material, the key causes in the means to eliminate the error "Your connection is not protected". Guided by them, you can correct the problem with this error and can further use your favorite Internet browser.

Browsers improve and are becoming increasingly advanced, but it affects safety only in a slight degree. Mainly the exchange of information comes from the client to the server and vice versa. Protecting data is not always possible with built-in means, as a result there is a risk that sent packages will receive an extraneous face.

Due to the insufficient level of connection protection, SSL technology has been developed that fills the need. Thus, the server and the client creates a specific key that is needed to understand all requests. Without this key, the intercepted data is not worth anything, namely, this was the key goal of the technology.

When SSL for any reason does not work correctly, you can see your error. Your connection is not protected by Firefox. Browser, defining the level of site protection, checks the accuracy of the basic parameters. If a step is incorrect, an error appears.

Most often the culprit that your connection is not protected by Mozilla, the server itself becomes. There are a number of situations in which the actions can be taken on the client side.

Error definition

Before proceeding directly to solving the problem, it is necessary to identify it. You can not think about doing the methods presented in the instructions and expect a positive result, but it is better to view the error code.

Having learned the failure code, it becomes obvious for what reason your connection is not protected How to fix and is it possible to influence the certificate processing. This information is available directly on the error page, you need to click on the "Advanced" button. The auxiliary failure parameters will be indicated, namely the reason for the cliff of the connection and the error code, the function that has found the problem.

Working with date

There are several options for problems that are associated with an incorrect display of time on the computer. At the same time, the time zone is processed correctly, that is, it does not matter the difference in time between the user and the client along time zones, but only the reference value.

Therefore, if the time is set to incorrectly and instead of installing GMT +3.00, the value of GMT is set to +2.00 and the time is transferred manually for an hour additionally, then the error will not wait. This approach is fundamentally incorrect and need to set correct parameters.

Faced with a malfunction, the "Certificate of Expite" or "will not be valid to", it is necessary to pay attention to the correctness of the specified time.

So your connection is not protected by Firefox, how to fix:

• Click in time in the lower right corner;
• Select the "Change Date and Time Settings" link;

• In the "Time Zone" section, click the "Edit ..." button;
• Select the correct belt, it is desirable to find your country among those listed, otherwise at least others, but with the same Longitude GMT;

• Click to "change the date and time";
• Specify the correct values \u200b\u200bbased on a reliable source, it is better to take from the network.

An alternative that will be a little easier to operate is to automatically update via the Internet. This method is available in the "Internet Time" tab. Next, click "Change Parameters ...". Then install the checkbox "Sync with the server ...". By default there is a server, but you can set different from it.

Disable antivirus

Sometimes the user faces a problem due to the presence in the anti-virus system with active protection. Usually this is evidenced by an error in which it is indicated that the chain of certificates is unknown. The problem of what your connection writes is not protected is in the presence of a built-in web inspector. It conducts additional manipulations with SSL, which are crowned with failure. It is logical that you can easily turn off this function.

If Avast is installed in the system, then you must configure:

• Navigate to the main menu of antivirus and click on "Settings";
• Further into the "Active Protection" tab;
• Follow the "Web Shield" section;
• Remove the flag from the "Enable HTTPS scan" item.

For Kaspersky action slightly different:

• Follow the "Settings" and deploy a complete list;
• Now find the "network";
• In the column "Scan of secure connections" it is necessary to remove the corresponding flag.

Creating a new certificate file

When none of the procedures helped, you can resort to another method. It consists in removing the certificate file and its further creation. It is likely that the cause of lags when your connection was not protected, there are failures in this file. You only need to remove the item, creating automatically.

So your connection is not protected what to do:

• Go to the menu and click on the question mark corresponding to the "Help" section;
• Next, follow the "Information for problem solving";

• Follow the Application Information tab;
• Go to the certificate folder;

• Fully close the browser;
• Delete the CERT8.DB file.

After automatically creating an item, the problem must disappear, as the bugs from the file are removed.

Alternative method

In any case, if you do not want to correct the fault, you can always go to the site, just ignoring the message. In a situation where the self-signed certificate is even recommended.

To despite the warning, go to the site, you must click on "additionally" and make a resource to an exception. The action must be carried out only if you fully trust the site, otherwise it is easier to go to another resource with a similar content.

Error message

At the end, if no methods still allowed to achieve the result, it is necessary to take off responsibility, because the problem is not in the user system. If possible, please inform the owner of the resource about the presence of a characteristic problem, it is better to specify the error code and message. Wait for the final site repair and the malfunction will disappear.

You can also inform about the problem and the technical department of the browser itself, they will probably be able to provide full assistance in solving. The required Count Notification is under the message, just highlight it.
