For some time now - two or three weeks - I experience R_END_OF_FILE_ERROR on many websites. It is only under Firefox. And not on all sites. One example is coronavirus.bg. I can't open it under Firefox. I use Firefox v.75 on Windows 7. I tried:

  • checking TLS settings - screenshot attached. Seems fine.
  • clearing the cache; didn't help.
  • turning network.dns.disableIPv6 to 'true'; didn't help.
  • turning network.dns.disablePrefetch to 'true'; didn't help.
  • restarting Firefox with add-ons disabled; didn't help.
  • scanning for malware; Malwarebytes didn't find any.

I am also attaching my browser test results from ssllabs.com.

I honestly don't know what to do and what is the issue. Please advise.

被選擇的解決方法

OK, I 'solved' the issue myself. Turns out the option DNS over HTTPS is what caused the problem. Although I don't really understand why.

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.

Thank you FredMcD. I have few more questions:

Here you are giving me an entire search result. Which specific link are you pointing out to me?

It is obviously not my ISP since other browsers do open these same websites. I already stated that in my initial post.

That would be quite unpleasant. Can you open this website that I gave as an example? And which Firefox version are you using?
