I downloaded Firefox 4, but when I tried to move it into the Applications folder, I was refused permission. I tried to post this problem to this forum and received a confirmation link by e-mail, but it failed: I got the message "Something is wrong."

If you get an error message that you do not have sufficient permissions to update then easiest is to trash the currently installed version to do a clean install of the new version.

Download a new copy of the Firefox program and save the DMG file to the desktop

  • Trash the current Firefox application to do a clean (re-)install
  • Install the new version that you have downloaded

Wow! It worked. Thank you so much. Saved me a trip to the Apple store. So glad to have Firefox back.
