I decided to get uber geek on my browser SO I downloaded firefox extensions (using "minefield") remember to right click and save the .xpi's in case you want to be able to reinstall quickly... (you can then use auto-update to bring your version up to snuff)
relative tab (hacked install.rdf to include 3.1.* fire gestures (which is similar to opera but very cool)
Options lets me customize them (duh, it's firefox!) I chose by the gestures most used (is there a way I can measure this?) so when I hold my right button down things happen (and to think, I'm a command liner from the DOS days)
page-up = up page-down = down
open in new back tab = left open in new fore tab = right
back = left up forward = right up
reload = up down (my modification, i only want "skip cache refresh)
next tab = up right prev tab = up left
new blank tab = left right
close tab = down right
scroll to top = left up scroll to bottom = left down
with speed dial I had to add the url with all defaults on and then go back and disable all refresh and dynamic stuff (bad browser! bad!)
