You can check the ssl and tls prefs on the about:config page. If any ssl or tls pref is bold (user set) then right-click that pref and choose "Reset" to reset the pref to the default value. Paste this regular expression in the Search bar at the top of the about:config page:

  • /security.*ssl|security.*tls/

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.


You can also try to delete the cert8.db file in the Firefox profile folder to remove all intermediate certificates that Firefox automatically stores when you visit a web server.

You can use this button to go to the currently used Firefox profile folder:

I have been out in the freezing weather and bought my lottery ticket!!

I will wait till my son comes over, he does technical things. So far nothing seems to work, no boxes come up to press run or install.

Will leave it for now

Thanks
