In Safari's Preferences, go to the Advanced tab and check "Show Develop menu in menubar"
Then when you're on a web page, go to Develop -> Open Page With -> Firefox

What a great tip...thanks. I have always used Safari but sometimes have run across a site that works better with FireFox (although much less often now) and it's always been a pain.
Interestingly my first time testing "Open Page With" it included Real Player and something I don't even have on my drive (at least Spotlight can't find it) - Opera.
