Hacking Mozilla

[a_colorado at ureach.com (Alexandro Colorado)]

I am a constant user of Opera, one of the best features is that I am able to go back and forth with click on the 2 buttons of the mouse. (Right then left takes me back, left then right takes be forward) I wonder if there is a way to hack into mozilla to do the same effect. I dont know how many people on this list hack their software but thats a nice feature to have on every browser.
