Do you have the new timeline interface activated in facebook ? This is probably a dupe of bug 712883

i didn't enable timeline for my profile. It happen in news feed page. besides that, while playing flash movie in facebook or any website contains flash movie, flash movie is lag is compare to google chrome. I think it is something related to javascript. p/s: while happening any lag i found that cpu usage very high

I confirm. It is not only facebook problem. Firefox had the awesome scroll on Google Reader until google changed it's design. Now it's fully impossible to work with GReader with FX (I had to use external RSS reader).

Checked on Nightly UX 12.0a1. The same problem. Changing smooth scroll doesn't help.

Enable Smooth Scrolling in GReader Settings (Experiments tab) doesn't work.

Yet Another Smooth Scrolling extension solve problem, but this: https://www.google.com/support/forum/p/Chrome/thread?tid=7f68043bcf0e8ad2&hl=en is history already.

I agree. No changes even in version 21 :( This bug blocks this: "Become a market leader in performance" (https://wiki.mozilla.org/Platform/2013-Goals) Please confirm this bug and make smth. P.S. Try GReader with Chromium if you think it's OK with FX.

Getting a profile using the builtin profiler in 21 might help diagnose this problem: https://developer.mozilla.org/en/Performance/Profiling_with_the_Built-in_Profiler

my profile in attach (if it can help). I have: Firefox UX latest build, Windows 7 x86 Steps used to create profile: 1. start UX, login to GReader 2. Scroll 100 unread items All add-ons and plugins were disabled (except Gecko Profiler 1.11.19, Flash 11.6.602.108 and Silverlight 5.1.10411.0) 3. Press 'Analyze' 4. Save profile to local file.

Thanks for the profile, mihal. For future reference, it's usually more convenient to analyze if you upload the profile and dump the link in the bug instead.
