If you have 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 DMG file to the desktop
- Firefox 6.0.x: http://www.mozilla.com/en-US/firefox/all.html
- Trash the current Firefox application to do a clean (re-)install
- Install the new version that you have downloaded
