Remove the "Your connection is not secure" message for Mozilla Firefox.

Mozilla Firefox is considered the most stable browser that lacks stars from the sky, but it does its job well. Unfortunately, Firefox s can occasionally run into all kinds of problems. Specifically, today we will talk about the "Your connection is not secure" error.

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

The message "Your connection is not secure" that appears when you try to access a web resource means that you tried to access a secure connection, but Mozilla Firefox could not the certificates for the requested site.

As a result, the browser cannot guarantee that the page being opened is safe and therefore blocks the transition to the requested site by displaying an unpretentious message.

Method 1: setting the date and time

If the problem with the message "Your connection is not secure" is relevant to several web resources at the same time, the first thing to do is the correct date and time on your computer.

Windows 10

1. 1. Click on «Start» with the right mouse button and select "Options" .

1. Open the Time and language section .
2. Activate the item "Set time automatically" .
3. If after that the date and time are still set incorrectly, deactivate the parameter and then set the data manually by clicking the button "Change" .

Windows 7

1. 1. Open the "Control " . Change the view to "Small icons" and click on the link "Date and Time" .

1. In the window that opens, click on the button "Change date and time" .
2. Using the calendar and the field to change the hours and minutes, set the time and date. Save the configuration with the button «OK» .

After completing the setup, try to open any page in Firefox.

Method 2: configure the antivirus job

Some Internet security antivirus programs have SSL scanning enabled, which can cause Firefox to display the message "Your connection is not secure."

To see if your antivirus or other security software is causing this problem, pause it and then try refreshing the page in your browser to see if the error is gone or not.

If the error disappears, the problem really lies with the antivirus. In this case, you just have to disable the option in the antivirus that takes care of the SSL scan.

Avast Settings

1. Open the antivirus menu and go to the "Configuration" section .
2. Open the section «Active protection» and, next to the element "Web Shield" , Click the button "Set up" .
3. Uncheck the checkbox "Enable HTTPS scanning" and then save the changes.

Kaspersky Anti-Virus settings

1. Open the Kaspersky Anti-Virus menu and go to the "Configuration" section .
2. Click on the tab "Advanced" and then go to "Network" subtab .
3. After opening the section «Analyzing encrypted connections» , you will need to check the box next to the item "Do not scan encrypted connections" , after which you can save the settings.

For other antivirus products, you can find the procedure to disable encrypted connection scanning on the manufacturer's website in the Help section.

Method 3: system scan

Very often, the message "Your connection is not secure" may appear due to the action of antivirus software on your computer.

In this case, you need to run a deep system scan for viruses on your computer. This can be done both with the help of your antivirus and with a special scanning utility, for example Dr.Web CureIt.

If the scan results reveal viruses, disinfect 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 the certificate data. It can be assumed that the certificate store is corrupted and therefore we will try to remove it.

1. Click the menu button in the upper right corner and select "Help" .
2. From the secondary menu, select Troubleshooting information .
3. In the window that opens, in the column "Profile folder", Click the button "Open folder" .
4. Once in the profile folder, close Firefox completely. In the profile folder, you will need to find and delete the file cert8.db .

At this point, you can start Firefox again. The browser will automatically create a new copy of the cert8.db file, and if the problem was a corrupted certificate store, it will be resolved.

Method 5: update the operating system

The certificate verification system is carried out through special services integrated into the Windows operating system. Such services are constantly being improved and therefore if you do not install updates for the operating system in a timely manner, you may encounter an SSL certificate verification error in Firefox.

To check for Windows updates, open the menu from the Control  on your computer and then go to Security and System - Windows Update .

If updates are found, they will be immediately displayed in the window that opens. You will need to complete the installation of all updates, including any optional ones.

Method 6: incognito mode

This method cannot be considered a solution to the problem, but only a temporary solution. In this case, we suggest using a 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 start incognito mode in Firefox, you need to click on the browser menu button and then open the item «New private window» .

   2. From the tab General ission , scroll down to la section proxy . Click on el button Setup .

Method 8: by lock

And finally, the final reason, which is manifested not in several protected sites, but only in one. You can say that there are no new 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 you can avoid being blocked, provided you are absolutely sure that the site is safe.

1. Below the message "Your connection is not secure", click the button "Advanced" .
