Canvas 3d JS Library

I wanted to try and see if our library will work any better (or rather, how much better) wth tracemonkey instead of the current javascript engine. I got a copy of the relevant branch and built it, but that wasn’t happy with the extension, because the extension has a max version in it that’s too low.

So I installed the nightly tester tools, and overrode the version check.

Sadly the result is that irefox crashes when I go to a page with a canvas3d on it. I rebuilt firefox with debug enabled, and this is what it told me:

++DOMWINDOW == 11 (0x145be80c) [serial = 14] [outer = 0x145acfd0]

Long story short, the extension uses stuff in Firefox 3 that no longer exists in current versions. I guess there’s also a possibility that the tracemonkey branch is very much out of date, but I’m having trouble believing that.
