Is it just me or did the Firefox canvas performance drop by 80%?

Judging by the comments and my own results, it really was just him.

Firefox graphics are just ridiculously slow for me lately, and I think it's because I'm not getting any hardware acceleration under Ubuntu. I wonder if you're having a similar issue.

My attempts to cajole Firefox have so far resulted in nothing more than flickering UI elements.

He mentioned in response to my comment that he doesn't have full hardware acceleration, which is probably why his results differ from so many others'.

it's likely there was some form of regression in canvas. i noticed one several months back here https://bugzilla.mozilla.org/show_bug.cgi?id=746773

on my nightly FF build i'm getting 70k fps, Chrome nightly gives my 85k

>70k fps

what?

> It will display an FPS count (Fillrects per second).

So not exactly "frames". The author is getting around 480k FPS in Chromium.

Meaningless benchmark. From comments it sounds like he's trying to identify a regression in software rendering performance for Canvas, but drawing single pixels using fillRect isn't a very good way to do it.
