I was logged into a website which hanged and when I tried to log back on it started giving me the error PR_END_OF_FILE_ERROR .I've tried to troubleshoot with all the help I could get on these pages and others, I'm at my wits end. The website works on my phone browser, so it's clearly this laptop or my internet dongle.
It's also happening across all browsers. I don't have VPN or antivirus software on except Microsoft Essentials. I've tried removing real time protection on that but it didn't work. I tried creating a new profile of Firefox, nothing. I tried going to about:config page and setting security.ssl.enable_ocsp_stapling to false, nothing so set it back to true I've gone to task manager to see whether there is a task don't recognise so I can stop it, nothing. Pleeeease heeeelp meeeeee!

Maybe I should add I'm on Windows 7.
Also on Firefox version 81.0.2 (32-bit).
radi.stoyanov said Turns out the option DNS over HTTPS is what caused the problem.
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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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.
Thank you Fred for responding, I've been searching and trying new things.
- DNS over HTTPS: I tried to click on that, restarted the browser, it didn't help. - Re: the cipher suite - what is this and how can I check it? What should it be set to and how to I do that? - Server outdated - How can I check this? It was working fine, I was in the middle of surfing when it froze and I had log out and when I tried to log back in it gave me this error. - I don't think the problem is limited to Firefox, as I'm unable to get to the same website on Chrome, Edge, IE and Firefox. I'm still logged into my account via my phone and it works well there.
I need someone who can talk me through some checks.
With regards to ISP was blocking sites how can I check this? It's only social media.
I've run the SSL Labs check, and I have a bunch of results, what do I do now with them?
You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").
Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of involved files.
If you revisit a 'forgotten' website then data for that website will be saved once again.
Mu cookies and cache are already cleared. I don't think this is the issue. Besides my FF is set to delete cookies, cache, history, the lot, each time I exit, so that's not the problem.
