Since your latest so called update a few days ago, all I get is the "Secure Connection Failed - An error occurred during a connection to www.youtube.com. PR_END_OF_FILE_ERROR" message when trying to open any pages. Your browser has become less useful than explorer or edge. It's the same message no matter what page is attempted to open.

Firefox isn't even good enough now to use to download a functioning browser. SMH

Hello,

This error may occur for many reasons. One is that these websites are being blocked. Another is because of cipher issues. Another (likely the issue) is DoH (DNS over HTTPS).

To disable DoH, scroll to the bottom of about:preferences, click network settings, then disable DNS over HTTPS option.

For more information about DoH, please see DNS-over-HTTPS (DoH) FAQs

Thanks for the response. I made the change you suggested and the sites have opened again. So far, so good. It's just aggravating the issue never occurred until they pushed the latest update a few days ago. Thanks again for your help.

You can try to disable DNS over HTTPS.

You can check the connection settings.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Today, I updated to version 96.0.3 (64-Bit) for Mac, and I have the same issue with many different (but not all) websites. I turned off the 'Enable DNS Over HTTPS' and it resolved it.

However, resolving that issue means now I can't use the 'Enable DNS Over HTTPS' feature!

I've been having the same problem with numerous sites including large, national banks who obviously are up to date on their network security. The unchecking DoH DNS over HTTPS worked. Can you provide an update that allows DoH, when available, otherwise use DNS over Http? Thank you
