I updated Firefox to 95.0.2 . Now Youtube won't load and I get the Security Failed error page with code"PR_END_OF_FILE_ERROR" . However, Youtube loads fine in my other browsers. Why is this happening?

radi.stoyanov said Turns out the option DNS over HTTPS is what caused the problem.

cor-el said This usually means that Firefox wasn't able to find a cipher suites to use to connect to this server and reached the end of the list. There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.

You can check your browser and possibly compare this with the server setup. https://www.ssllabs.com/ssltest/viewMyClient.html
