Trackpad switch pages with 3 fingers
No.

All you can have is to activate both the 2-finger and the 3-finger gestures. They work differently, though.

With two fingers you scroll the page to the sides revealing the page "below" it or the page "above" it according to the tag history.

With three fingers you just tell the browser to "go back" (swipe left) or "go forward" (swipe right) without any animation at all. At least this 3-finger gesture is consistent in many apps, including Finder.
