Whenever I try to install the upgrade I get this error message: The operation cannot be completed because you do not have sufficient privileges for some of the items.

I have the previous version of Firefox installed but whenever I try to install the downloaded upgrade I get the error message:-

"The operation cannot be completed because you do not have sufficient privileges for some of the items."

When I try to use the update function in the 3.6.11 I get the message that I need administrator privileges.

I have a MacBook Pro and am the only user.

You can try to repair the permissions for the Firefox application files and folders, but it is easier to do trash the current version and download and install a full copy of the new 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.
