Secure connection failed message
I cannot use Firefox to browse any more, because it refuses to load gmail and/or youtube. These are sites I have used thousands of times in the past, but recently Firefox will not let me go there any more, and it says "secure connection failed." It also says I should "contact the website owners" to inform them of this problem. (Good luck contacting Google!) Seems like this must be an error, since I have used those sites many times in the past. I have looked at this page of Mozilla's: https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect But it is too long and technical for me to deal with. Anybody have any suggestions about how to get Firefox to not freak out when connecting to a Google service?

Please explain the problem in detail. What happens? What is/are the exact error message(s) ?
There is security software like Avast, Kaspersky, BitDefender and ESET that
intercept secure connection certificates and send their own.

Screenshot attached of what happened when I tried to launch youtube using Mozilla Firefox. That is ALL that happens - this message shows up and the browser refuses to launch youtube.
Screenshot did not upload after several minutes; trying again.
Looks like screenshot (a png file) will not load. The screen says this: Secure Connection Failed
An error occurred during a connection to www.youtube.com. PR_END_OF_FILE_ERROR

Then there is a blue box that says "Try again" The address bar at the top of the page says https://www.youtube.com -- but I did not type it in with the "s" designation; I only typed youtube.com
My security software is called Vipre.

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 There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.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