So Useful Rated 5 out of 5 stars

Really speeds up browsing.
Instead of moving the cursor all the way into the corner, you just click, drag, and let go to go back.
One of my favorites is to use the rocker gestures to switch tabs. This feature is great, and so is the one to close a tab. That little x on the tab is soooo small, and I can set any gesture to immediately do that action.
It does take a little getting-used-to, but this addon is great if you want to speed up your browsing speed.
