How to fix the error: “Your connection is not secure” for Mozilla Firefox

Mazila is one of the most popular open source browsers. It includes many functions and is available for users of all popular operating systems. Developers are constantly improving the security system, but as a result, this leads to some limitations. As a result, we see the message “Your connection is not secure”. This error prevents access to the site and indicates that certificate validation failed or encryption is not suitable for security requirements. This means that the page is not safe enough to visit, attempts to gain access will lead to vulnerabilities and a likely risk for the PC or communication channel. Follow our guide step by step in order and it will definitely fix the problem.

Check the date and time on your PC

Datetime validation is due to the fact that most websites use certificate expiration validation.

• Right click on the clock in the lower right corner and select Set DateTime.
• Set the time manually or click “set time automatically”.
• If auto time is turned on, press Off, then turn it back on.
• Restart Mozila.

Restart your router

The router also causes a similar problem.

• Find the power button and hold it down until it turns off completely.
• Wait at least 30 seconds.
• Turn it on, wait for the connection and check the site.

Check the system for malware

The error is often the result of an infection of the operating system with a virus or spyware. Perform a full scan with your antivirus program or use the standard Windows application.

• In the start menu, write “defender”.
• Select the type of check – Full, and start the scan.
• After completing the procedure, check to see if the problem has gone away.

Clear your browser history

Mozila stores all visited sites (URLs), passwords, cookies, etc. in history. To clear the saved history:

• Click on the 3 horizontal stripes in the upper right corner.
• Select “Privacy & Security”.
• Then click on “Clear your recent history” in the history section.
• Click “clear now”.

Disable your antivirus temporarily

Antivirus and its settings are one of the causes of the problem. Try disabling SSL verification . If for some reason this is not possible, temporarily disable your antivirus and try to gain access again.

Use private mode

When you use private mode, no one (whoever has access to your PC) sees your activity. Except for saved links and downloaded data, no history is saved.

• Click on the 3 horizontal bars in the right corner of the screen.
• Select a new private window.
• Then try again.

This option is available using the hotkeys Ctrl + Shift + P.

• Check your link in the private window.
