So I just re-installed Windows 7 and I'm reinstalling everything. I use to have Firefox setup on my laptop so that if I clicked a link with my left and right mouse buttons simultaneously it would open a link in a new tab and if I left+right clicked a tab it would close the tab. How do I get that back? I thought I had set it up through All-One-Gestures but I can't find it in that so I guess that wasn't it.

I know, I had the exact same problem. I downloaded Chrome and called it a day.

When I got my new computer a month back it was pre installed on 7, same problems . I did what AJ suggested and also called it a night as i'm not really good at setting features the way i want them to be.

ummm, doesn't middle click do that by default?

yes.

If you left click on a link, firefox should also open it in a new tab by default.

I'm on a laptop so I don't have a middle click, I can only click with both buttons at the same time.

And I don't want to use Chrome because I just don't like it.

Are you sure it wasn't a system/touchpad setting rather than a Firefox one? I can't remember having that in Firefox itself, but on my laptop the software for the touchpad has a "emulate third button" option which is left+right simultaneous click.
