I would love to update Firefox, but the software update window goes nowhere and never downloads the update. I have tried this running both Snow Leopard and Lion on my Macs.
That's it - I get the window that says downloading Firefox, connecting to update server, but it never goes anywhere past that - the ribbon keeps spinning.

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
- Firefox 7.0.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
Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.
