Hello. After upgrading to ver. 82 FF won't start, there is now browser window visible, just an hourglass spinning for 1-2 seconds and nothing afterwards. In Task Manager I can see a problem being sent, I have 55 such messages all pointing to faulty ntdll.dll, here is the content of one of the latest:

I'm now using ver. 81 because nothing else worked, I tried the clean install method but it was just a waste of time. Thank you.

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}
