@GingerbreadMan,
I can not go to about:support because with newer versions of firefox on linux it completely crashes, even locking up my desktop, forcing me to hard reboot my machine.

If its that simple to crash firefox and the entire desktop, then firefox fully sucks.

That sounds like a hang, not a crash. If it happens in a brand new profile, ask a new question on the support site and see if someone can help you.

I have seen it both hang (locks up my mouse), and outright crash (segfault)

The pixelation appears to be the sizes of the canvases differing between browsers, which is generally the fault of the webpage.

Nightly 41 and Chrome Canary are about the same speed for me.

Please attach to this bug a copy of the about:support page in Firefox.
