After my update, the finger gestures on my touch pad do not work in FireFox nor does multi-links. (both I use regularly) If FireFox does not get it fixed soon I will be using chrome more.
I have those same problems with Finger gestures when ever I see Obama or Pelosi or Reid on TV telling lies! When the gestures don’t work I am compelled to yell out FU. My wife is sometimes annoyed.
Another Firefox software update this morning seemed to address all my issues. One I didn’t mention yesterday was that in YouTube the visual format in Firefox was in disarray and that is now back to normal. Hopefully the new update will address your issues also.
