For me, on Windows 7, it's 22 FPS in 13.0.1, 14.0b10, Aurora, and Nightly (same window size, new profile).

Thanks.

Does anyone have an XP machine this can be tested on?

I do - is that helpful?
I guess the extent of what I could do would be to help pinpoint the build where the problem started occurring, and test new builds to see if the problem is fixed
I can't reproduce this on my WinXP thinkpad. I get exactly 15 FPS on the July 5 Nightly, and exactly the same on the June 19 Nightly as well as in current Aurora.
Btw this is on a ATI Mobility Radeon HD 3650

Certainly if you could bisect this down to one day using archived Nightly builds, that would be very helpful.

I'll do it this weekend
OK - I'm baffled.... Going back over many nightlies is yielding the same result. I'm even seeing the same result on the latest release version. Have tried uninstalling and reinstalling everything including DirectX and graphics drivers - to no avail. Everything else using DirectX 3D is still runnning just fine. Any ideas?
I tried every single build back to the the beginning of June. Damn this annoying. A curse on you Windows
Have you tried a clean Firefox profile? (firefox -P -no-remote)
Unfortunately yes... no different. Just tried a v15 nightly too... same results. Going to do some more investigation on this machine - something must have changed. Probably fairly safe to say this probably isn't a problem in firefox
Some ideas for you to look into -- since the 310M is a mobile chipset, are you plugged in?  If so, did your power settings change to use a lower performance setting even when plugged in?
