Hi, I have a Mac 10.11.6 and for whatever reason I cannot get Firefox to open. I received a message at the bottom of my browser during the last use saying something to the effect of click restore/restart to improve speed. I did this and now Firefox will not open. I get a Mozilla crash reporter screen even when I try launching it in safe mode. I tried the refresh option (by holding shift + option on startup) and still get the crash report screen. I reinstalled it multiple times, tried deleting it and doing a clean install, deleted my profile and created a new one, and even deleted my anti virus program. Nothing seems to be working and I am very eager to get my preferred browser working again.

Thanks very much for your insight!

Five days ago, I started to see unwanted advertising, including unwanted pages and pop-ups when using Firefox 54.0 on an iMac running OS X 10.11.6. Firefox stopped unwanted pages while loading, but those pages still needed to be closed manually. At the same time, web pages began to display double-underlined hyperlinks that would activate pop-up ads. These adware symptoms are not present when using Safari. Today, I trashed the infected Firefox and downloaded version 54.0 again, but the adware symptoms were present again. Thanks for any help. Ron

MacbookPro OS 10.11.6

  1. About a week ago Firefox was running no problem.
  2. Closed Firefox (quit)
  3. Re-opened and got the Profile missing error.
  4. troubleshoot through existing threads on mozilla support. including renaming the profile.ini file, deleting it, moving it, etc.
  5. Used Appcleaner to wipe all known goodies of Firefox from my computer
  6. downloaded a fresh 76.0.dmg from the website
  7. Problem persists. Application does not load, "Profile missing" opens immediately
  8. No application support data in /Library/ application support/firefox exists

Chrome works and Safari works no problem.
