How many nights have you laid awake wondering how can i expend even less energy surfing the net?
Well worry no longer because firefox has done it again.

All-in-one gestures is a firefox extension that allows you to control the web browser without all that pesky moving to click a button.

You simply hold down the menu button on the mouse and draw a litle line and it translates the little line and does what you want. For example a line travelling left would take you back a page and a line travelling forwards would take you forward a page. Up and left or right to navigate through the tabbed windows.

It would require an initial effort to download the extension but after then the saved energy would surely make up for it.
