Two finger swipe works in Chrome Dev version, but backwards. Swipe right to go back?
> System Preferences > Mouse or Trackpad (which ever you're using)
In the drop down menu under "swipe between pages" choose "swipe with one or two fingers" if you're using a magic mouse or choose "swipe with two or three fingers" if you're using a trackpad.

This will let you keep the nice swiping animation in Safari and also let you keep navigation everywhere else.
