For the last week or so, I can't connect to website using Firefox. I have refreshed Firefox several times and then I can connect. However, if I close Firefox and shut down my computer, the next day I can't get to websites. I get an error message: Secure Connection Failed
An error occurred during a connection to mail.yahoo.com. PR_END_OF_FILE_ERROR
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.
I am able to use other browsers to get to the websites. What can I do? Is there a fix? I have used Firefox for years without a problem. I have many sites bookmarked but now I can't get to them.

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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