Firefox 4 requires at least OS x 10.5, you can get Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

but I'd like to be able to revert back and have all my bookmarks intact. I was looking through my disk utilities but am not seeing the solutions. Am I out of luck? Will I just have to reset my bookmarks? thanks

Thanks for the link to the 3.6. Downloaded easily with all bookmarks intact. Seems to be working faster than the origibal as well

Perfect! This works!!! Mozilla... remember many Mac users keep machines a looooong time! They are like an old Mercedes. They never die.
