Secure Connection
I just updated Firefox beta version to 94.0b9 and now I can’t seem to go to some websites. Like “support.mozilla.com” - “accounts.firefox.com” - “addons.mozilla.com” I get an error message “An error occurred during a connection to “support.mozilla.com” PR_END_OF_FILE_ERROR The same thing happens with many other websites that I need to go to. I had taken a screenshot of the message but I can’t upload it! because I can’t go to this website from my Desktop PC, so I am doing this report from my iPhones browser.
Thanks for your help.

That shouldn't happen with Mozilla websites.
You can check the connection settings.
- Settings -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
See "Firefox connection settings":

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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. https://www.ssllabs.com/ssltest/viewMyClient.html
Enable DNS over HTTPS setting isn’t checked off.
Use system proxy settings. is selected and if I use No proxy settings nothing works at all.
Note: You know that I can’t click on the links that are given because I am not using my desktop PC I am using my iPhone to communicate and get support from you.

What are the computer's proxy settings? Are you using a VPN?
Have you thought about using the normal Firefox? http://www.mozilla.org/en-US/firefox/all/
The PC system settings are “use automatically detect settings and there’s no proxy set” the VPN is set at the default settings. I can not connect to any type of financial websites and any your websites too. I don’t know how to set up a proxy anyway.
Thanks
I don’t like not being able to answer your reply’s from my email account.
I try using my computer other browsers and I got the same problems/issues
Start Firefox using Troubleshoot(Safe) Mode {web link}
A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?
