microGesture од snuz2

Why do we need another mouse gesture extension? It seems that there used to be a handful of Mouse Gesture extensions for Mozilla products, but lately they have dwindled down to about one. While FireGestures can be configured to do almost anything, I don't like its philosophy at all, so I wrote microGesture.
I believe that mouse gestures are only really useful for the most common tasks of the browser, especially, forward and backward navigation. I also added top and bottom of page as well since they are intuitive and handy gestures and open and close tab. About the only other common task I perform when browsing is following links, so I added gestures that intelligently respond to links and allow you to take control of where they open: in a new tab, or in a background tab. Using more complicated gestures is no easier than right clicking to get a context menu plus they're a pain to remember.
