Details

I'm testing a long page where I have to scroll up and down a lot. To scroll I use my trackpad on OSX Mountain Lion with two fingers. Scroll direction in OSX is set to "Natural". After a while scrolling with two fingers stops working. Not just on the page I'm scrolling, but every page in every tab. Opening pages in new tabs or new windows doesn't solve the issue. Only restarting Firefox solves it. Scrolling in other applications works just fine, it's only Firefox. I noticed the problem today in 29.0 and it's still happening in 29.0.1 which I updated just now. I can still scroll with the scroll bar, which does show up when I try to scroll with two fingers. Scrolling stops working on every scrollable element, not just the body. The textarea I'm typing this in doesn't scroll either. Left and right scrolling is affected as well. It seems like I'm not the only person affected by this bug: http://twitter.com/jaycardhoe/status/464269992129601536
I found out what triggers it: scrolling left or right with two fingers immediately results in two finger scrolling not working anymore. Happens every time.
Tested on a year old Macbook Air. It does not happen there. On the computers I have at hand it only happens on my recent Retina MacBook Pro. Tested in Safe Mode just to be sure, but it happens in Safe Mode as well.
Further pinned it down. In the System Preferences -> Trackpad -> More Gestures. When Swipe between pages is checked the bug occurs. If it isn't, it doesn't occur. Still, only on my Macbook Pro. On the Macbook Air there is a smaller bug I tested it again on the Air and it seems that the unwanted behaviour does occur. But it occurs there only once: 1. Swipe left and right 2. Swipe up or down. The first time you swipe up and down, nothing happens, after that all works fine. This behaviour also only occurs when Swipe between pages is checked

I can confirm this bug happens on my iMac running 10.9.3 and only occurs when Swipe between pages is checked. This bug occurs on both a Trackpad and Magic Mouse.
I'm having the same issue using Firefox 29.0.1 on MacBook Pro (Mid 2010) running OS X 10.9.3.

This just started happening to me today. I suspect this is a Core::Cocoa Widgets bug.

This sounds a lot like bug 927702, which is an Apple bug. But I understand that only happens on OS X 10.9. Those of you who see this, test also with other browsers, especially Safari.
This is a bad bug, regardless of who's it is. I can't use Firefox on my machine now, restarting it only gets rid of the bug for about one minute. So far I haven't hit any problems with Chrome. We need to stay on top of this and do what we can to solve it or work around it.
Josh, please let us know anything even slightly unusual about your computer -- software or hardware. If I'm right that this is bug 927702, it's been around for a long time and I've never seen it.
Josh tells me he also sees problems in Safari ... though apparently not in Chrome.
Josh, do look in the system console for any messages that might be relevant -- when you see this problem with either FF or Safari.
I keep a pretty vanilla system - nothing special about it, few applications that don't come with the system, no extensions or unusual plugins in Firefox, nothing special about the hardware, no peripherals attached. Maybe the only slightly non-standard thing about the configuration is that I use full disk encryption. I didn't change anything about my computer today either, was just doing the same sort of work I do ever day when this problem hit. The last time I updated something was installing the MacBook Air EFI Firmware Update 2.9 on June 23rd. I don't see the same problem in Safari, what happened is that I went to reproduce in Safari and a two-finger side swipe froze the browser. More specifically, it froze the content process permanently, half way through the back animation. I could still use the URL bar, but I could not navigate away from the frozen page. So not the same bug, but it's entirely possible that something fishy is going on with two finger swiping.
Anything interesting in the system console when you see the problem?
It would be really cool if somebody who can reproduce this would run mozregression[1] to see if one of our commits has caused this issue to appear, or caused it to occur more frequently. Just like Steven, I'm still unable to reproduce this myself. [1] http://mozilla.github.io/mozregression/
I ran into this a couple times yesterday. No idea what the cause was.
Just throwing this out here, hoping it might help someone with the diagnosis of this and similar 10.9 problems: iTerm2 recently had to switch to building with the 10.9 SDK to prevent glitches with multi-monitor support. For more info, see/ read: https://code.google.com/p/iterm2/issues/detail?id=2885
I've already said it a couple of times above, and I'll say it again: Please look in the system console (using the Console app) for any interesting messages that appear when you start seeing this problem, or just before. I suspect this bug may ultimately be a hardware problem, and that this may show up in the system console. Before you start looking for console messages, it's probably best to restart your computer. This will make the problem go away, temporarily. Then when it comes back, you may see signs of it in the console. Don't just report any message. Look at the messages' timestamps first (they all have them).
(In reply to comment #17) If you see this bug and have a two-monitor setup, please try the following: 1) Detach your external monitor and restart your computer. 2) Use only your built-in monitor for a while. See if this makes the problem go away.
I just had this happen to me again. I was not using an external monitor. There's nothing suspicious in the system console. Scrolling still works fine in all the other applications.
Is this a dupe of bug 927702?

I know this is a very old report but I believe this is in fact a duplicate of Bug 927702 which has already been fixed so this should be closed as well.
However, if this issue is still reproducible please feel free to re-open.

Thanks!
