Synaptics Pointing Device two finger scrolling randomly fails in Firefox 4 RC
I have an HP Envy laptop with a multitouch pad that uses two-finger scrolling gestures. In Firefox 4 RC, this gesture stops working from time to time. I do not believe the touchpad drivers are at fault, since gestures continue to work in other applications and I have restarted the device to no avail. Restarting firefox clears the problem. I did not have this problem in Firefox 3.6.x.

Partial Solution!
I have determined the cause of this problem (though I can't be sure it is the only cause of the problem.) If there is a .pdf file open in any tab, two finger scrolling stops working except for that tab. Closing the tab also solves the problem.
However, this just means that I have a more specific bug to report, then, that the scrolling gestures do not function properly when a .pdf is open (with Acrobat viewer) in any tab.
Not sure if they automatically take bugs reported in these forums over to the Bugzilla site or not....let's hope so.
THANK YOU!! Man, that was really bugging me. Noticed that it still worked fine in Thunderbird and that's when I figured out it was Firefox. Closing the PDF tab and now it's working like a charm.
