If you are browsing with Firefox, you may come across a certificate error that usually comes with an ‘Invalid Certificate’ or SSL error. This is because Firefox automatically attempts to validate any websites that show a certificate for your security. 

So, what can you do to keep Firefox from rejecting these sites and giving a certificate error?

  1. Click on the Hamburger

    Now click the ‘Encryption’ option from the options provided. In the encryption window, click the ‘Validate’ button. Remove the checkmark next to ‘Certificate Validation’ and click ‘Ok’.

    From now on, Firefox will accept all certificates without validating them first. You will no longer get an ‘Invalid Certificate’ error when trying to gain access to different sites.

By following the above steps, you will resolve the certificate error when using Firefox. You can get back to exploring different websites without fear that your browser will block them because of a certificate or SSL validation error.

Why not try following these steps the next time you get a certificate error and see how quickly it can be fixed.
