Connection to https sites

Ever since the most recent update to Firefox I consistently get the following message when attempting to login to https sites which I have been connecting to for years: Secure Connection Failed

An error occurred during a connection to www.att.com. PR_END_OF_FILE_ERROR

Error code:PR_END_OF_FILE_ERROR 

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Clearly the problem is with Firefox and not with the website owner since it occurs with all websites.

I found over 100 instances of PR_END_OF_FILE_ERROR but the few responses I looked at were back in 2021 or 2022. One solution suggested clearing the cache which I did and I was then able to connect. But now that does not help. Is my only reliable solution to delete Firefox and use some inferior browser?

You can try to disable DNS over HTTPS.

Are you using a proxy or VPN?

You can check the connection settings.

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

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

See "Firefox connection settings":
