Canvas Debugger in Firefox Developer Tools

This looks pretty similar to the venerable WebGL Inspector extension.

One bonus is that this is fully-remoted with our debugger protocol. In time, we hope to get the asset inspection parts included in our tool as well.

We'll also be showing Nick Desaulnier's port of the WebGL Inspector for Firefox in our booth at GDC!

Chrome also has a canvas debugger tool. You have to jump through some hoops to get at it: http://www.html5rocks.com/en/tutorials/canvas/inspection/

Edit: Looks like it's been fixed in the new build today. Thanks!
