I've ran into out of memory errors on Firefox with canvas heights greater than 8000, chrome seems to handle much higher, at least to 32000.

EDIT: After running some more tests, I've found some very strange errors with Firefox 16.0.2.

First, I seem to get different behavior from in memory (created in javascript) canvas as opposed to html declared canvas.

Second, if you don't have the proper html tag and meta charset, the canvas might be restricted to 8196, otherwise you can go up to 32767.

Third, if you get the 2d context of the canvas and then change the canvas size, you might be restricted to 8196 as well. Simply setting the canvas size before grabbing the 2d context allows you to have up to 32767 without getting memory errors.

I haven't been able to consistently get the memory errors, sometimes it's only on the first page load, and then subsequent height changes work. This is the html file I was testing with http://pastebin.com/zK8nZxdE.
