found this little beauty who is also portable: http://www.strokesplus.com/ been using it for a few hours. works pretty good but you have to use LUA scripts to program your gestures. it is also under steady development. tested in Win 7 and Win 8.
Yep, Fire gestures is the first extension I always install in Firefox, surfing becomes so time consuming and boring without it
on Linux, EasyStroke is very good! folks, if you are not using mouse gestures you are missing a lot. i don't know how much time i have saved so far; creating tabs, closing them, closing apps, minimize them. all that with a simple gesture, without having to aim for a 5 x 5 pixel button to so simple things.
