Bonjour, Do you speak English?

Google Translate:

Hello, since my last update a lot of error messages: SSL_ERROR_RX_UNEXPECTED_APPLICATION_DATA ou erreur

PR_END_OF_FILE_ERROR

SSL_ERROR_RX_MALFORMED_ALERT .... etc

How to correct these errors? Thank you

Are you running Linux, Windows, or Mac? Can you provide steps to replicate the issue? What version of Firefox?

Google Translate: Utilisez-vous Linux, Windows ou Mac ? Pouvez-vous fournir des étapes pour reproduire le problème ? Quelle version de Firefox ?

Hello, your browser provided some unusual information in its identification (user agent string):

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0/CmfozreS-21

Does that sound like it might be related to any software on your computer?

Do you have Avast security software ?

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

Same Error Messages since one of the most recent AVAST and windows 10 updates. When I click try again it opens the page. It does it indiscriminately on different webpages. Not a virus, I've run 2 different full scans from malbyteware and avast. I wonder if MS doesn't want us to use anything but their Virus and firewall protection. LOL!

This could be a problem with Avast Anti-Track, so if you use this software then try to disable it.
