After the page loads on treeherder.mozilla.org, I started the profiler in FirefoxDeveloperEdition.  Then I just scrolled up and down on the page.

The frame rate dropped to below 20 for a good portion of that.  Looking at the profile, 93% of that is in "Graphics".  Profile attached.

Seems like this might be a good candidate for a test bed for Firefox speed improvements.

I'm on a mid-2012 Macbook Pro with 16GB RAM, fwiw.
