You keep tempting me with updates. I run 4.0b8. When I try to put it in my application folder, I get the message that I do not have certain privileges.

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
