Just wanna say that EVERYTHING @Jan Keromnes has answered is EXACTLY what I'm feeling. I've been a loyal Firefox user since around 2001. I live the net through it. In the very least, being able to *enable* this behaviour - if only through "about:config" - is very, very important to power users. PS: It's not a good idea to assume that users will have mice with horizontal scroll, nor is it guaranteed that if they have horz-scroll on the mouse, that they'll actually use it that way. I have a Logitech G700 and I've mapped copy/paste to my left/right horz-scroll cause that's what I use practically once every two minutes while working.
