Comment 43 for bug 1099289

I found that when this happens, Firefox also stops to respond to clicks - real mouse click, not only touch-pad clicks. And that this doesn't happen to other software like Nautilous, and that this happens only in firefox, not on its titlebar (which traditionally is part of a window-manager - things changed so much nowadays I don't even knnow how to address it now). I am guessing this behaviour ascribes to this bug -- it happened twice on my tablet, and if it keep happening I would be able to say for sure.
