Just did a fresh install of Ubuntu 12.04 on my laptop and noticed that the middle-click (actually three finger-tap on the touchpad) on Firefox doesn't work as it used to. When doing it on a link it doesn't get opened on a new tab, in fact, it doesn't get opened at all. Only the (useless) window size and position controls appear, as demonstrated on terminal in the following screen shot.
How do I get my tab-opening middle-clicks back?
TapButton3
setting resets to 0. Any idea how to solve this? – hleinone Jun 09 '12 at 21:19
