When I try to use Firefox 72.0.2 I cannot connect to ANY website. I just get an error message that says:

Secure Connection Failed.

An error occured during a connection to website.com PR_END_OF_FILE_ERROR

Hi dave.kydd, I assume non-secure connections are okay? For example:

http://www.example.com/

The PR at the beginning of PR_END_OF_FILE_ERROR usually refers to a proxy or "man in the middle" of your browsing connections. That might be a security software filter or something else. Sometimes it is a problem with a VPN.

Does anything in the support article help with tracking it down: Secure connection and security warning error pages in Firefox.
