Revision Content

When a website you visit attempts to secure communication between your computer and the website, Firefox cross-checks this attempt to ensure that the certificate and the method the website is using are actually secure.

Some websites try using out-dated (no longer secure) TLS mechanisms in an attempt to secure your connection. Firefox protects you by preventing navigation to such sites if there is a problem in securely establishing a connection. When this happens, you will see an error page with the option to report the error to Mozilla.

report tls error
If you experience this problem, contact the owners of the website and ask them to update their TLS version to a version that is still current and still secure.
