[Bloody Sam Roberts]

I'm either going to have to uninstall this version, if I can, or use System Restore to get rid of it.

Frustrated by happenings like this and other disasters that lunched my Firefox, I wrote a quick batch file that will copy the whole Firefox profile directory and another to restore it back.
I keep a shortcut to them handy next to my Firefox icon and use the backup often. It's a real hair saver.

BSR, that's really good advise. Prior to upgrading, it is really smart to back up all your preferences. For Linux users, this is really easy.

tar czvf mozilla.20051129.tgz .mozilla

If your settings get borked, to back out:

rm -rf .mozilla
tar xzvf mozilla.20051129.tgz

I don't use windows, so I'm not sure where that stuff is kept.

Along the same lines, I do essentially the same thing. My /usr/local/firefox directory is a symlink to the version I'm currently using.

To go from version 1.0.7 to 1.5:

(as root)
rm firefox ln -s /usr/local/firefox-1.5 /usr/local/firefox

If I need to go back, I do the same thing but point to the previous version number instead.
