Sorry for my poor English (I'm learning it).
I've searched on Google and on Super User any way to configure Firefox 8 to scroll horizontally with a regular mouse (2 buttons + scroll wheel), but I could find only solutions that don't seem to work anymore (like that one: http://twob.net/journal/fixing-horizontal-scrolling-in-firefox/).
I would like to be able to scroll a page horizontally scrolling the mousewheel while pressing the SHIFT key. (SHIFT+Mousewheel default action is going back and forward in the browser's history).
For your information, I'm using Firefox 8 under Ubuntu 11.10 (I'm not sure if the O.S. is relevant in this case).
Appreciate any help.
