When downloading, I am never connected to the update server. It will say it is connecting, but nothing else happens.
I will get a pop-up message that I need to update Firefox. I click the button, and it says it is 'connecting to the update server'. It never connects, because nothing else happens. Even after an hour or two, it is still 'connecting to the update server'. If it matters, I am on a Mac.

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 5.0.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.
