When I try and install 4.0 I get the following error message: The operation can’t be completed because you don’t have permission to access some of the items. How can this be?

Not sure what else to add. I have tried several times to install version 4.0 but get the same message every time. As an open source browser I don't understand why such a message would appear. I have a Mac Air with the latest OS.

If you get an error message that you do not have sufficient permissions or have other problems with updating to update then easiest is to download the full version and 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
