Firefox offered to create a new profile for me, but took forever to do so so eventually I had to shut off the computer. In restarting, initially Firefox would not open as "Profile could not be found". Having moved Firefox to my trash folder, when I attempt to install Firefox again, it completes the download, then does not appear in my Applications folder.

This is likely caused by a problem with the profiles.ini file and the profile marked as Default=1 in this file is not present on the hard drive.

  • Mac: ~/Library/Application Support/Firefox/

You can use one of these to make Firefox create/use a new default profile:

  • Delete the profiles.ini file to force Firefox to create a new default profile
  • Use the Profile Manager to create a new profile
  • Use "Choose Folder" when you create a new profile to select the location of a lost profile and recover this profile

Download and save the full Firefox installer to the desktop and start the installation with a double-click on the desktop icon.

You can find the full version of the current Firefox 29.0.1 release in all languages and for all Operating Systems here:
