Hello. On some of my sites that i try to get onto with Firefox its says performing TLS handshake then it goes to Secure Connection Failed and says PR_End_Of_File_Error. I am totally updated with Firefox, plus i cleared out everything in my history. That did not help. When i tried to get onto these websites with Chrome web browser i do not have this problem at all. Why is this? I have BitDefender Total Security newest version for home. My firewall is through them along with virus protections. So can you help me out with this ongoing problem getting on some websites?

Thanks Firefox [email removed from public]

Hey there!

The PR_END_OF_FILE_ERROR error message appears when the Mozilla Firefox browser can't establish a secure connection and it is a Firefox-specific error.

Try the following: 1) Disable your BitDefender as it is quite common for security software to be "overcautious". 2) Refresh Firefox. Hamburger menu (at the top right) -> Help -> More Troubleshooting Information -> Refresh Firefox (top right). 3) Disable/ turnoff your VPN or proxy. It may be interfering with the connection.

Hope I helped!

See this reference (remove the blank space). You should at most use refresh as an absolutely last resort. This article covers many more points.

You can create exceptions to DNS over DOH.
