I've used Firefox on this same Mac for several years without a problem. Suddenly, this morning, the browser stopped working. Since then, I've cleared cookies and cache, and uninstalled and reinstalled Firefox. Still, no matter the website I try to connect with, I get the same message, "Hmm. We're having trouble finding that site." According to Mozilla, my Mac OS, 10.14.6, is still supported. Help!

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

I should also note that Chrome seems to be connecting to internet, but Safari is not. My version of Firefox is 94.0.1.

Thanks, Fred. As with so many of these issues, I'm not sure what solved the problem. I just kept throwing ideas, including yours at it, then turned off the computer, let it rest, and -- amazingly -- I'm back in business. I think you were on to something about security protocols, however, since Safari and Messages both went offline, as well as Firefox. Thanks for your help, R
