After having the issue with my photos being blocked on Facebook, I was told I needed to upgrade to the newest version of Firefox and that the version I am currently using (3.6.3) is no longer supported with security updates. I have tried to follow the steps in the upgrade process through Firefox itself, but have been unable to do it...I would love step by step instructions to walk me through it as I don't know what I am doing wrong.bold text

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.
