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.

How do I default spellchecker to the primary Mac OS dictionary?

The built-in Firefox spellchecker is woefully inadequate. It's tagging very common words as misspelled. How do I point the spellchecker to the primary dictionary used by … (funda kabanzi)

The built-in Firefox spellchecker is woefully inadequate. It's tagging very common words as misspelled. How do I point the spellchecker to the primary dictionary used by my computer (Mac OS)? Thanks in advance!
