Firefox 3.5b4 has the 3 finger gestures built in. They also have a 2 finger gesture for swipe up/down that takes you to the top or bottom of the page.
 
I'm loving multiclutch with firefox 3. I have three finger swipe set to switch tabs and rotate left and right to go back and forward in the browser. Fastest internet surfing ever. I wonder if the novelty will wear off, but for now, it rocks!

I've been using multiclutch with firefox since i first got my unibody in october. I think completely practical, I almost can't live without it. Freaks the heck out of anyone else who uses my computer though. I always get "what is wrong with this thing?" I usually say tell them that they are the problem.
