I use Firefox 18.0 with Xubuntu 12.04 on a lenovo Laptop T60.
I like to use the middle button above the touchpad to do a middle-click on a link to open that page in a new tab. It works with the mouse and it worked with my former laptop, a Thinkpad T41 with very similar touchpad.
I can open a link in a new tab too if I hit the left and right button meanwhile, but that's not comfortable.
I find this with synclient:
synclient -l

I guess LTRB stands for left, top, right, bottom - MT for middle-top is missing.
Btw: Middle Click for pasting works. I'm curious how that fits together.
I'm sorry, but while experimenting, I found it to be my own fault: I asked myself
Seems to be a hardware problem. If I hit the button hard and short enough, it opens links in new tabs. I'm sorry and provide a self-answer, if maybe this hardware problem is not too rare. Since refurbished Thinkpads are quite common, it might be helpful for others.
Middle button on a ThinkPad has two modes of action:
middle click
andscroll with trackpoint
.Clicking middle button quickly causes a middle click action while holding it down and using the trackpoint allows you to scroll whatever is under the cursor.
This is a hardware feature and requires no support from OS.
