User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1163.0 Safari/537.1

Steps to reproduce:

On the nightly UX builds, if you use the two finger back/forward gesture, once the page is loaded, scrolling on the trackpad doesn't work until you move the mouse.  Once it moves, the scrolling works again.  It's as if the scroll gesture is not being received by the new window.

It seems to only happen if you try to scroll too soon before the page is fully loaded again.  But once you try to scroll, even once the page is loaded, the scrolling doesn't work until you move the mouse.

I can confirm that this bug affects

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:25.0) Gecko/20100101 Firefox/25.0

for me it always fails once any two finger swipe gesture is used regardless of if it is during page load or not and it stays broken regardless of if the mouse is moved or not.

I have temporarily worked around it by disabling two fingered gestures altogether but this is non-ideal.

I tested this on MacBook Pro OS 10.9 and following the reporter's steps, I can reproduce this on Nightly 46.0a1(2016-1-13) but I can't reproduce it on Firefox 43.0.4, so this is a regression. 

Using mozregression lead me to:

Paul, David, has this issue continued for you?

ovidiu, if Bug 1193062 - [APZ] Use PanGestureInput events to trigger APZ scrolling on OS X - caused a regression, it seems to me a new bug should be filed because this bug report well predates Bug 1193062

I have tested in Firefox 44 and I can't reproduce it. Based on comment 6 and 7 I will close this as Resolved: Works for me. Please feel free to reopen it if are able to reproduce this bug with the latest Firefox release version.
