Firefox fails to load certain sites
Firefox fail to load certain site with message Secure Connection Failed An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR
I tried all the Mozilla support options: clearing cache, refreshing firefox, load in trouble shooting mode, reinstall and problem still exists. Other browsers don't have problem

This should not shut my internet connection down, should it? I had a problem just after I tried this. But it appears to be working now. Thanks for the quick help

Hello,
This error can be caused by many things, but I think that the easiest one to try to see if it is causing issue is DoH. It is a measure that although secures your dns queries, may not be the best, as errors like this may crop up. To disable this, go to about:preferences#general and find the network settings. Click on change settings and turn off DNS over HTTPS.
More information about DNS over HTTPS can be found at DNS over HTTPS (DoH) FAQs

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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