It's firebug.

And I narrowed down what causes it to crash:

http://l.yimg.com/pb/webplayer/0.9.20/js/player-min.js

Simply including that url in a script tag (put nothing else on the page - 
just the single script tag) will cause an instant crash.

Took a huge number of restarts, but it's firebug and that file (but other 
files also cause it - it was very hard narrow down exactly). I also 
checked the plugins to firebug (firecookie) and that didn't make any 
difference.

I ran it with the firebug console open (in a debugger to freeze the 
display when it crashed) and nothing was printed except 1 cookie change.

player-min is huge, and I didn't try to narrow down exactly what in it 
causes firefox to crash.

But one thing that confuses me is that it doesn't always crash. 
http://webplayer.yahoo.com/get/ includes that file, yet doesn't trigger a 
crash.
