With a trusted Internet site where the Uniform Resource Locator (URL) begins with “https://,” the Internet browser is required to check the validity and relevance of the certificate and the adequacy of the level of encryption for user privacy. If such a check does not give positive results, the Mozila search engine will stop trying to establish a connection with an unverified Internet portal and issue an information alert “Your connection is not secure.” This does not mean that this website is potentially dangerous and can cause harm to the user. global network, stealing personal data, and to the computer, introducing malicious software or viruses into it.
Cases where users encounter a message in the browser Mozilla Firefox“Your connection is not secure” can be different. Let's look at the most common options in order to be aware of the risks and be able to eliminate this problem, if necessary.
One of the scenarios when you may encounter a denial of access to network resource and see the message “Insecure Firefox connection” may occur due to incorrectly set date and time. In this case, the user can check the relevance of their settings and correct them by setting the settings for automatic time synchronization. This problem can be especially acute for residents of Russia twice a year, when other countries switch to winter or summer time. And the Windows operating system can rearrange the time on its own. In such cases, it is worth revising the time zone.
Also, standing guard over the user device antivirus programs may prevent you from accessing certain websites. The activated Secure Sockets Layer Scan feature may be to blame. You can try disabling this SSL option to conduct an experiment and try to access the site again. In this case, the risk of running into trouble increases. From the same category, it is possible that the computer is already infected with malicious software. Required full scan system for its presence, followed by a complete cleaning of the PC.
Note: Problems with verifying SSL certificates may be due to the absence or irrelevance of certain components built into Windows OS itself. Don't forget to check for updates and install them on your computer in a timely manner. operating system. In the “Control Panel”, in the “System and Security” item there is “Center” Windows updates", where you can check for updates and, if available, install them.
If with date and time and also with security personal computer Everything is fine. An experiment with disabling the SSL option in the antivirus did not produce results. You can try cleaning the certificate store. To do this you need to find and delete specific file"Data Base File".
Mozilla Firefox browser settings => Open Help menu icon => Troubleshooting information.
In the profile folder, open the resources with the saved data, find the “cert8” file and delete it, after closing the Mozilla browser.
After launch search engine this file will be created automatically, and the certification problem may be resolved.
The following method does not eliminate the error, but allows the user to bypass browser restrictions. To do this, you should try using the “ ” option.
This method will allow you to bypass restrictions and will not store in the browser any information about the user’s activity on the Internet, cache memory, cookies and your location.
The most common situation when the Mozilla Firefox browser displays the error “your connection is not secure” occurs when connecting via Wi-Fi networks with Proxy server settings, where you need to use a login and password. In this case, you only need to add a security exception, obtain a certificate and use all the features of the progressive Internet browser.
Sometimes, quite often, when users try to log into a certain Internet resource, they receive a message that an error occurred while establishing a secure connection. How to fix such a failure will now be discussed. Depending on the situation, several different techniques can be used.
What does it mean: “Error establishing a secure connection”?
First of all, you should clearly understand the problem of such a failure. The essence of the error is that when accessing a specific site, the system needs to check the SSL certificate used for the HTTPS connection in order to establish the identity of the publisher.
However, several situations can be clearly identified when such a check gives a negative result, as a result of which a message is displayed stating that an error occurred when establishing a secure connection:
- discrepancy between the date and time on the computer and the Internet settings;
- outdated or expired certificate;
- certificate with incorrect serial number;
- OCSP server errors;
- incorrect browser settings (most often Mozilla Firefox);
- blocking by the antivirus.
Let's consider several typical situations.
Error when establishing a secure connection: how to fix it in the simplest way?
Let's start with the most primitive way to fix the problem. As mentioned above, the time set on the computer may not correspond to the Internet settings. Therefore, these settings need to be changed.
Some users try to set the date and time directly in Windows, this does not give the desired result, and the error when establishing a secure connection appears again. Why? Yes, only because the configuration must be done in the primary BIOS input/output system. Then you can still count on something.
Disabling SSL and installing a certificate in antivirus
Antiviruses, compared to a firewall or Windows Defender, are much more likely to block such connections, considering the connection to be unreliable.
The solution to the problem can be either temporarily disabling the protection, which is not very convenient, or setting the appropriate parameters. As a rule, such a section is located in the network settings. Here you need to disable SSL verification, and then use the “Certificate Installation Wizard”, which will evaluate the validity of the connection, after which you just need to install the certificate. After confirming successful installation, the problem should go away.
Fixing errors in browsers using the example of Mozilla Firefox
With browsers the matter is somewhat more complicated. As a rule, the message that an error occurred when establishing a secure connection is most often issued by the “fire fox”.
You can correct the situation as follows. First, with the browser disabled, go to Explorer and go to your profile set for the browser (the profile folder is located on system disk in the directory with the user name of the Users directory, where you need to go to the AppData directory, then - Roaming, then - Mozilla, then - Firefox, after that - Profiles, finally -
Note: additionally, in the tls_tickets security parameters, you can double-click the parameter value to false. Just in case, you can check whether the blocking extension AdBlock is enabled.
Problems with torrent trackers
Torrent trackers, as you know, are not particularly favored by the governments of many countries, believing that such sites only host pirated content. This is partly true, but not always. One such resource is the NNM.Club tracker. An error when establishing a secure connection appears quite often.
The tracker itself is now serviced exclusively at two addresses - 81.17.30.22 and 193.201.227.16. If something different is returned when pinging an address, it means that a spontaneous redirection is occurring. In this case, you just need to clear the DNS cache, see if there are any entries for these addresses in HOSTS file at the very bottom of the text, finally, you can simply set exclusion rules for these IPs in the antivirus or firewall.
As a last resort, if it is problematic for an ordinary user to do this or the solution does not help, instead of a torrent file, you need to download the so-called magnet link and run it in the appropriate torrent program. In principle, the same applies to other trackers.
Mozilla Firefox has long been considered one of the most popular, reliable and convenient Internet browsers. However, even it is characterized by some critical failures, due to which performance suffers. Among such failures, one of the most unpleasant can be considered a “secure connection error.” It occurs when you try to access a page on a website. In this case, access to the page, and sometimes to the entire site, is blocked.
The main reason for the “secure connection error”
The error message literally looks like “Your connection is not secure” and appears only when you try to access a specific Internet page. The common reason for its occurrence is a critical failure in the process of checking electronic site security certificates by the Mozilla Firefox browser. These certificates are responsible for activation automatic connection via the secure HTTPS protocol, which should ensure the safety of users’ personal data: numbers credit cards, IP addresses, passwords, etc.
When an error occurs, a corresponding icon in the form of a yellow triangle also appears at the top of the window.
There may be several reasons why security certificate verification may fail. Depending on the specific reason, you should choose one or another way to solve the problem.
The main thing you need to know in this case is that reinstalling Mozilla Firefox will not solve the problem.
Causes and solutions related to Mozilla Firefox browser
If such an error occurs, you should first look for its cause directly in the browser. There are several options here.
Checking operation in incognito mode
Sometimes it happens that the requested Internet resource itself is not able to provide a security certificate (for example, the site says engineering works), in which case the user does not need to do anything. Just wait a while and try loading the page again. If you need to access the site at any cost, you can try to do this using the built-in Mozilla Firefox tool - “incognito” mode:
Adding a site to the exclusion list
This method is the most “humane” and does not require any serious actions from the user. All you need:
- Go to the browser, enter the address of the requested site and after the “secure connection error” appears, click the “Advanced” button.
The “Advanced” option is only available when a “secure connection error” occurs (it cannot be found in the settings menu)
- In the additional notification window that appears, click on the “Add exception” line.
The error description will also indicate that invalid security certificates are being used
- Next, after entering the full address of the site, click on the “Confirm security exception” button.
Don’t forget to also put a checkmark next to the line “Permanently store this exception” so that you don’t have to manually add the site to the list of exceptions each time
- Done, restart your browser and access the site without interference. Now the certificate for this site will not be verified.
Disabling a proxy server
This method is suitable if a security certificate error occurs when visiting several sites at once. By disabling the proxy server in Mozilla Firefox, you can resolve the error for all resources at once. However, this method can be considered too radical, since a proxy server is a kind of “protective intermediary” between the user and the requested site, whose responsibilities include masking the user’s personal data, in particular, browsing history, personal IP address, etc. Therefore, by deactivating this tool, you will also partially give up anonymity on the Internet. But if you still decide to resort to this remedy, then you need to do the following:
- Open Mozilla Firefox and then go to the Settings menu.
There is no hotkey combination to open the settings window in Mozilla Firefox
- In the main settings window, select “Basic”, then scroll down the ribbon to find the “Proxy server” option and click the “Configure” button.
Remember that the “Proxy Server” setting is in the “Basic” category, and not in the “Privacy and Security” category, as it would be logical to assume
- Place a checkbox next to the “No proxy” option and click OK.
You can also disable the proxy server for specific sites by entering their full addresses in the “Do not use proxy for” column
- Done, you can now access websites without having to check security certificates.
Corrupted “certificate store”
As you already understand, every time you visit Internet resources, Mozilla Firefox checks their security certificates. In order not to go through this procedure again for previously visited sites, the browser creates a special “certificate storage” on the system hard drive, where all successfully received and processed data is stored. However, such storage may become damaged (for example, in the event of some system failure on your PC), resulting in the error “Your connection is not secure.” Therefore, one of the most effective ways there will be a solution to the problem complete removal"certificate stores" with hard drive. For this:
- Open Mozilla Firefox and follow the path “Settings Menu - Help - Troubleshooting Information”.
The Troubleshooting Information section is located in the Help menu
- In the browser “profile” that opens, find the line “Profile folder” and click on the “Open folder” button.
The Troubleshooting Information window contains all the main Technical information about the browser
- Find the cert8.db file in the folder and delete it.
Before deleting the cert8.db file, be sure to close Mozilla Firefox
- Done, you can now launch the browser again.
Disable SSL certificate verification
SSL (Secure Sockets Layer) is a special Internet protocol that provides a secure connection to the World Wide Web by encoding outgoing and incoming data. The Mozilla Firefox browser has the ability to disable this check for any specific site.
This is done like this:
- Go to your browser settings menu and enter the “Privacy and Security” section.
The “Certificates” option will be at the very bottom of the list
- Find the Certificates settings option and click the View Certificates button.
By default, SSL certificates are checked automatically and regularly for all sites
- In the certificate management window that opens, go to the “Servers” tab and select “Add an exception.”
The Servers settings window lists valid SSL certificates
- Next, in the “Address” line, enter the Internet address of the problematic site, then click the “Get certificate” and “Confirm exception” buttons.
Before confirming, do not forget to click the “Get certificate” button
- Done, now SSL certificates will not be checked for the excluded site.

Causes and solutions associated with PC problems
If none of the above-mentioned methods for eliminating the “secure connection error” have brought positive results, then you should look for the cause of the failure in your PC or in the software installed on it. Let's look at the most common cases.
Resetting date and time settings
This option is relevant when the “secure connection error” is widespread and appears when trying to load several different sites. In most cases, the Date and Time problem occurs on Windows 10. To fix the problem on Ten, you should:
- Click right click on the Start menu icon and go to Settings.
You can also access Settings through Control Panel
- In the settings window that opens, select the “Time and Language” category.
There are no hotkeys to quickly open the Time and Language settings window
- Then go to the “Date and time” parameter and opposite the “Set time automatically” line, move the “scroll button” to the “On” position.
You can also additionally activate the option “Automatically set time zone”
- Close the window and restart the PC.
If you have Windows 7 installed, then you need to:
- Open the “Start - Control Panel” menu.
The required settings parameter is located in the “Control Panel”
- Go to the “Date and Time” section.
The Date and Time settings window can also be opened by right-clicking on the clock in the bottom panel Windows tasks 7 and selecting the “Settings” line
- In the settings window that opens, click on the “Change date and time” line, and then manually set the current date and time values.
If there is a failure in the date and time settings, the current date is automatically reset to January 1, 2012
I personally encountered the problem of date and time failure in Windows 7. If you manually set the correct date and time again, and after rebooting the PC, all saved parameters were lost again, then try again after the next manual settings, without closing the “Date and Time” window, go to the “Internet Time” tab and carry out additional synchronization with the built-in system application times.windows.com. To do this, click the “Change settings” button, then in the “Setting the Internet time” dialog box that appears, successively click the “Update now” and OK buttons. This solution may help in some cases.
Before clicking the “Update now” button, check the box next to the value “Synchronize with an Internet time server”
Setting up an antivirus
Another way to solve the problem with the “Your connection is not secure” error in the Mozilla Firefox browser is to set up an antivirus. First of all, you need to check your PC for viruses and malware, because there is a possibility that your browser is infected with a Trojan worm. After the scan is completed, you can try to disable the function of checking sites for security in the antivirus settings (this function is available in any antivirus program). Let's look at the shutdown algorithm using the specific example of Kaspersky Internet Security:
- Open the Kaspersky Internet Security start window and click on the “Settings” icon.
After change network settings in Kaspersky Internet Security there is no need to restart the PC
Kaspersky Internet Security also provides (like the Mozilla Firefox browser itself) a function for setting exceptions for specific sites, thanks to which you can not completely disable the scanning of secure connections. However, based on personal experience, I can say that such exceptions may not always work correctly. Problems begin to appear after updating the antivirus, when exclusion lists may disappear altogether and will have to be created anew. Therefore, if a “secure connection error” occurs, it is best to temporarily completely disable anti-virus connection scanning, go to the site of interest, and then reactivate the protection.

Operating system update
The Mozilla Firefox browser checks security certificates using special Windows OS system services. These services may be subject to failure, most often due to outdated versions software components of the system. Therefore, Windows needs to be updated periodically. If you have Windows 7 installed:
If you have Windows 10 installed:
Online security is one of the fundamental requirements of users when choosing a particular Internet browser. Mozilla Firefox provides everyone with many tools to protect their personal data. The function of one of these tools is to check electronic security certificates when loading an Internet page. However, even the most secure and reliable sites may fail this test for many reasons. Therefore, when a “secure connection error” occurs, users can be helped by the ability to configure both the browser itself and individual components of the Windows OS.
It is considered the most stable browser that does not have enough stars in the sky, but at the same time does its job efficiently. Unfortunately, from time to time Firefox users may encounter various kinds of problems. In particular, today we will talk about the error “Your connection is not secure.”
Ways to remove the “Your connection is not secure” message in Mozilla Firefox
Message "Your connection is not secure" appears when you try to navigate to a web resource, it means that you attempted to navigate to a secure connection, but Mozilla Firefox was unable to verify the certificates for the requested site.
As a result, the browser cannot guarantee that the page you are opening is safe, and therefore blocks the transition to the requested site, displaying a simple message.
Method 1: Setting the date and time
If the problem with the message “Your connection is not secure” is relevant for several web resources at once, then the first thing you need to do is check that the date and time set on your computer is correct.
Windows 10
Windows 7
After completing the settings, try opening any page in Firefox.
Method 2: Setting up the antivirus
Some antivirus programs that provide Internet security have activated function SSL scanning, which can cause the “Your connection is not secure” message to appear in Firefox.
To see if your antivirus or other security program is causing this problem, pause it, and then try refreshing the page in your browser and check whether the error has disappeared or not.
If the error disappears, then the problem really lies with the antivirus. In this case, all you have to do is disable the option in your antivirus that is responsible for SSL scanning.
Setting up Avast
- Open the antivirus menu and go to the section "Settings".
- Open section "Active protection" and around the point "Web shield" click the button "Tune".
- Uncheck the box "Enable HTTPS scanning", and then save the changes.
Setting up Kaspersky Anti-Virus
- Open the Kaspersky antivirus menu and go to the section "Settings".
- Click on the tab "Additional" and then go to the subtab "Net".
- Opening the section "Scanning encrypted connections", you will need to check the box next to "Do not scan secure connections", after which you can save the settings.
For other antivirus products, you can find the procedure for disabling scanning of a secure connection on the manufacturer’s website in the help section.

Method 3: System Scan
Quite often, the message “Your connection is not secure” may occur due to virus software on your computer.
In this case, you will need to run a deep system scan mode on your computer for viruses. This can be done either using your antivirus or a special scanning utility, for example Dr.Web CureIt.
If the scan results detect viruses, cure them or remove them, and then be sure to restart your computer.
Method 4: Delete the certificate store
On your computer, the Firefox profile folder stores all information about the use of the browser, including certificate data. It can be assumed that the certificate store has been damaged, so we will try to delete it.
From now on you can launch Firefox again. The browser will automatically create a new copy of the cert8.db file, and if the problem was a corrupt certificate store, it will be resolved.
Method 5: Updating the operating system
The certificate verification system is carried out special services, built into the operating room Windows system. Such services are constantly being improved, and therefore, if you do not install updates for the OS in a timely manner, you may encounter an error checking SSL certificates in Firefox.
For Windows checks To check for updates, open the menu on your computer "Control Panel", and then go to the section "Security and System" - "Windows Update".
If any updates are detected, they will be immediately displayed in the window that opens. You will need to install all updates, including optional ones.
Method 6: Incognito Mode
This method cannot be considered a way to eliminate the problem, but only a temporary solution. In this case, we suggest using private mode, which does not save information about search queries, history, cache, cookies and other data, and therefore sometimes this mode allows you to visit web resources that Firefox refuses to open.
To run in Firefox mode incognito, you will need to click on the browser menu button, and then open the item "New private window".
Method 7: Disabling proxy work
Using this method, we will completely disable the proxy function in Firefox, which may help solve the error we are considering.
Method 8: Bypass the block
And finally, the final reason, which does not appear on several protected sites, but only on one. It may indicate that there are no recent certificates for the site, which cannot guarantee the security of the resource.
In this regard, you have two options: close the site, because... it may pose a potential threat to you, or bypass the blocking, but provided that you are absolutely confident in the security of the site.
