Envious of your friend using cool mouse gestures in Opera ? No problem. With the power of add-ons in Mozilla Firefox you can add almost any feature to Firefox.
Fire Gestures is one such add-on which adds mouse gestures to Mozilla Firefox.
A simple mouse movement opens a new tab, another one closes tab and more …. You have to use it to get addicted to it.

You’re probably the last person on the internet to add mouse gestures to Firefox.
