I have been having problems with Firefox on my Mac so went for update and refresh. Firefox now won't open because it can't find my profile folder. I have located this and put it on my desktop. How do I now 'tell' Firefox where it is as I am still getting the same message?

Thanks. I finally sorted it following online Mozilla instructions very carefully. Appreciate you getting back.

You can copy files like these with Firefox closed to the current profile folder to recover specific data.

  • bookmarks and history: places.sqlite
  • bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
  • cookies.sqlite for the Cookies
  • formhistory.sqlite for saved autocomplete Form Data
  • logins.json (passwords) and key4.db (58+) or key3.db (57 and older) (decryption key) for Passwords saved in the Password Manager
  • if you only have key3.db then make sure to remove an existing key4.db
  • cert9.db (58+) or cert8.db (57 and older) for (intermediate) certificates stored in the Certificate Manager
  • if you only have cert8.db then make sure to remove an existing cert9.db
  • persdict.dat for words you added to the spelling checker dictionary
  • permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
  • sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder)

fyi for the future :

Please let us know if this solved your issue or if need further assistance.
