I keep getting a message of: "Unable to update Firefox 4.0, due to my not having system permission required to install update? Contact your System Administrator. I don't have one. It's my Desktop?"

  • Download a new copy of the Firefox program: http://www.mozilla.com/firefox/all.html
  • 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.
