First I tried to download Firefox 4 and was refused permission. Then I posted to this forum and received a confirmation link by e-mail, but the link failed.

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

Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.

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