Details
A security error is thrown when loading an image into a canvas element, then attempting to extract the image data back out using getImageData - even though everything is done on the same domain (in this case, the local domain). Works perfectly when hosted on a server.

This bug is causing considerable problems with users of Canvas libraries (notably Processing.js). I'm receiving a constant stream of questions and complaints, at this point, concerning this bug. Is there any way we could see a fix come in for 1.9.0.2?
Flags: wanted1.9.0.x?
This is an issue with file:// principals; this got changed, and I'm not sure what the right fix is. I'd ask bz next week (or remind me and I can do it).

Boris, any thoughts here?
This is the same issue as bug 444641 -- the easiest is to set the pref that boris mentions in bug 444641 comment #4.
