Mozilla mouse gestures

Optimoz provides mouse gestures for Mozilla (so you can hold down the mouse button and draw a line from right-to-left to go back, draw a lower-case H to go to your homepage, etc). They’re incredibly useful. I use them all the time at work in Moz. I can’t use them here at home, though, because I can’t get the installation to work under Linux. I’ve read the mailing lists and the big database, tried their suggestions, and it still isn’t working. I want y mouse gestures! ——-
