Firefox supportforum

‘I am finding that I cannot connect with sites I use because I keep geting a Secure Connection Failed message, this is becoming a nuisance, surely not every site I visit is insecure which inclides Linkedin and Newspapers and even the UK's National Lottery.

my windows version is 10 32bit. i have facing many time crashing problem with latest Firefox version ! so i completely uninstall Firefox & re install it but problem not solved. ! so i install old version 79.0 (32-bit). i relax with this version because it is more stable than latest one. it crash only when my system idle for long time !

Activity - I decided to add the AdBlocker Ultimate Extension to my FireFox. addons://detail/adblockultimate@adblockultimate.net During or after download it started to dispay a web page. FFox and my entire machine became VERY slow, and the message "TLS handshake with Google.apps" was displayed bottom let of the FFox Window. AFTER MUCH time, a "donate" page was displaed with various buttons and payment options. May be for a moment my Linux machine speeded up before going VERY SLOW,,, eventually a window poped up saying@ script "Chrome://browser/content/tabbrowser.js.5262" - do you wish to stop or continue,,, Despite clicking "Stop" lots of time, - which was difficult as mouse arrow movement was slow due to machine being slow / dead. EVENTUALLY - despite waiting long time for the Java Script to complete, I had to power off the m-c & restart. ... It is VERY FAR from good that Through any web page - that FFox can crash my machine... IMHO - TOTALLY DANGEROUS, and far from good. I have found this a very frequent problem, with FireFox crashing my Linux M-C Some web sites are better than others. Or rather some website will very quickly kill my Linux MC.
