Is the testcase passing a <canvas> to drawImage? If so, this is likely a duplicate of bug 705559.
Depends on: 705559

I'm not a Javascript developper but the testcases mostly do a lot of calls to a function called drawPart(), which is defined here : http://codef.santo.fr/codef/codef_core.js ...in which the calls to DrawImage() look like this : dst.contex.drawImage(this.canvas,partx,party,partw,parth,null,null,partw,parth);

Yeah, that's passing a canvas to drawImage for sure. Should retest once bug 705559 is fixed.
@lambin: please try again with Firefox 11+ I think this can be set to resolved/fixed
The link you provided is no longer available, can you please provide another one so I can test this on my end? Also, is this still reproducible on your end ? If yes, can you please retest this using latest FF release and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E). Thanks.
