You might like to try the internet browser opera. They have optional mouse gestures that make browsing a lot easier. For example: hold the left button, then click the right to go Forward; hold the right button, then click the left to go backward; hold the right button, move up then down to refresh a page, etc.

Pretty fucking nifty. It's also the fastest browser available currently. Source for that info is here: http://www.howtocreate.co.uk/browserSpeed.html#winspeed
