I'm on Aurora, so just upgraded to 21.0a2. On OS X, many pages scroll very badly, with latency before starting the scroll and choppy, slow, scrolling when it starts:

http://www.reddit.com/r/programming/
http://trac.edgewall.org/timeline

On the other hand, some sites scroll fine, including this Bugzilla.
On Facebook:

- My News Feed seems to scroll fine
- A user's timeline (once loaded) scrolls badly

This turned out to be due to the SmoothWheel plugin. The author is working on a fix.
