I upgraded my MacBook Pro (Intel) to Monterey 12.0.1 and now Firefox 94.1 will not access the internet - no error messages, just hangs. I have re-installed Firefox and Monterey but no change. Meanwhile Chrome works perfectly.

Any ideas?

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}
