The checkmarks in the drop-downs which indicate e.g. whether I can see CSS warnings or not very frequently do not show as checked when in fact they are "on". For example, at this very moment I can tab over to my Gmail window, see some CSS warnings in the console, then hit the arrow beside the CSS button, and neither Warnings nor Errors will have a checkmark next to them, even though they are clearly enabled. In fact, as I play at this very moment, I can't get any checkmarks to display at all in the Net or CSS tabs, yet the other two seem to be working okay. I'm on Leopard and ff4-rc1.
we need to review our tests in this case, this kind of thing does have coverage, perhaps not coverage with a higher rate of logging.

Indeed, and there's a bit more conversation there.
