When I move the Firefox icon into the application folder, I get the following message: The operation can’t be completed because you don’t have permission to access some of the items. Why and what can I do to complete the upgrade?

I am trying to upgrade from Firefox 3.0.3 to 3.6. I have downloaded as instructed but I am not allowed to complete the installation by moving the application into my Application Folder thereby replacing the older version.

  • 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.
