I try to update Firefox , but when I try to instal,the message 'zero K B available' what do I do? Also experiencing other problems with Firefox, like sudden blackout when watching TV , cursor freezing or no response when clicking on something. Is it a bug?

Try to repair the disk permissions:


If there are problems with updating or with the permissions 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 disk image (dmg) file to the desktop

  • 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 if you uninstall and (re)install Firefox.
