Every few days when i try to use Youtube or Google in Firefox i get the Error Message "Secure Connection Failed" and the Code "PR_END_OF_FILE_ERROR". This is very annoying and i did not find a way to fix this for me. The only workaround is using another browser. I have the Version 68.0.2

Try to make new profile via `about:profiles` and set it to default. If its working, export your bookmarks from the old profile and import them to the new profile.

Thx for the quick reply, i try that as soon as the problem reoccurs! Currently it is working again. (I dont know how to recreate it, so i have to wait)

It is working! (I synchronized the profiles via the Mozilla Account)

Thanks a lot!

Hi tanujashalu999

This means that Firefox wasn't able to establish e secure connection and that all cipher suites failed (i.e. Firefox reached the end of the list). This can happen if you use a proxy or VPN or have other software that intercepts the connection and act like a man-in-the-middle.

• https://support.mozilla.org/en-US/kb/error-codes-secure-websites

You can check the connection settings.

• Options/Preferences -> 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":

• https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

I had this same problem. Instead of losing all configurations, extensions and stuff, I just reseted checked the option Activate DNS on HTTPS, on network senttings menu.

I hope it solves this type of problem.
