Please spell this out in more detail.  I don't understand it as it
stands.

Please give detailed, step-by-step instructions.

This bug only happens occasionally. It only happens after a certain event though, and sadly does not always happen when I repeat the same process.

1. Open Firefox, and start using it.
2. I use the Mac multitouch touchpad with three fingers to swipe up, which expands open windows like seen in the picture http://winsupersite.com/site-files/winsupersite.com/files/archive/winsupersite.com/content/content/139776/lion_17.jpg
3. I click another window to go into a different application.
4. When I return to the firefox window, I am occasionally unable to scroll.

I do this all the time and am unable to reproduce this.  Please re-open if you still experience this with latest Nightly on 10.10 or later.
