Mouse gestures, opera had these back in the day. The right-left click to go back, ability to close a tab from anywhere on the page with just a single hand, etc.

Maybe it's no longer possible due to all the click hijacking introduced by web2.

Vivaldi and Firefox (via extensions) still have mouse gestures and there aren't any problems with it.
