I have version 75.0 of firefox. I was browsing as normal and it suddenly locked up. If I type in the address bar then search suggestions appear but nothing loads in the main window. Non of my favourites load. Clicking the new tab button doesn't load a new tab. The menu button opens but the options don't load. I have tried uninstalling. I have removed any sign of mozilla / firefox from my program files and program files x86. If I right click on the main window, the menu that appears has pretty much every option you could imagine. theirs so many option that it scrolls off the screen. on one occasion my laptop blue screened (which it doesn't normally do) but when it came back on firefox worked again until I turned the laptop back on again the next day and it was broke again

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

I have removed and readded firefox from the firewall following the guidance provided but the problem still occurs. If I download and install version 74 the firefox starts working again but it immediately starts to update it self to version 75 so when I close firefox and open it again its useless again.

How do you completely turn off update checks in Firefox v64?
You can use a policies.json file to disable updates for all users.

Same issue here.... Firefox v75 locks up and makes Windows 10 unusable to the point I have to force a shutdown. Sometimes it crashed after a long lock up. I have refresh Firefox and uninstalled and reinstalled it. I will post a crash log here and maybe someone can let me know whats causing it. Any help would be greatly appreciated. I love using Firefox and would like to get this fixed, thank you.
