Can someone help me with the PR_END_OF_FILE_ERROR

Posted

I am facing this PR_END_OF_FILE_ERROR problem from last 15 days, I tried EVERY possible solutions posted in different community supports (Microsoft, and firefox) and also checked every possible article on this problem but none of those helped me. I see firefox tries to do some "TLS handshake with the server" everytime before this problem apperars.

Then I tried a solution provided by a user in microsoft community, the suggested me to switch the proxy setting to "Auto detect proxy for this site" and "Enable DNS over https", and it was working for me. But from last 2 days I started facing the same issue again. The webpages only works when I start Firefox in Safe Mode.

It's so frustrating and makes it impossible to use Firefox. And leaves me with no other option but to use Microsoft Edge. I really like Firefox so wanted to know if anyone could help me fix this issue with something New and Effective.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

jamesafuf123 said https://support.mozilla.org/en-US/questions/1264659#answer-1237475 my ISP was blocking sites like that

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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