User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20130521 Firefox/24.0 (Nightly/Aurora) Build ID: 20130521031106 Steps to reproduce: 1) Load a new page so the position is at its top (not some remembered position). 2) Flick-tp-scroll to the top (even though the page is already at its top position). 3) Flick-to-scroll down Actual results: The page scrolls down a bit but stops early. Doing the flick-to-scroll down gesture again makes it work correctly. Expected results: The page should have scrolled down a lot more. It works correctly if you do the gesture again.
I'm trying this with inertial scrolling turned on in the OSX preferences (10.8.4), and then doing a two finger flick to scroll. Is that also what you're doing? I'm not seeing the same behavior that you describe.
Not sure about inertial scrolling: Where do you enable that in the preferences? The behavior is definitely still reproducable for me. Yes, I'm using 2 finger flick to scroll.
Since today's nightly (2013-08-22) I can't reproduce this behavior anymore. Seems like it got fixed with some other bug.
Probably due to the backout of bug 673875, which was prompted by bug 907275.
