text put into a canvas element with context.fillText() always has a black box where each letter goes. If the text is black you just see the black rectangle. If the text is not black you see it on the black bounding box. Surely this is not right.

This has happened on the last few versions of firefox, as long as canvas has been supported. I see other people's screen shots from canvas tutorials, and the text always looks normal. On my system, any text put into a canvas element via context.fillText() will have a black bounding box for each letter, sized appropriately for the letter. If the text is black, of course you only see rectangles. If the text is a contrasting color, then you can read it, but it looks bizarre.
