While the glass effect on black is somewhat neat, it could annoy certain people ;) Anyway, confirmed with Mozilla/5.0 (Windows; U; Windows NT 6.1; WOW64; en-US; rv:1.9.3a5pre) Gecko/20100531 Minefield/3.7a5pre ID:20100531040317.

Hmmm. A lot of weird things seem to be happening in fullscreen mode. I attached a screenshot for an example. Notice that none of the text looks the same. My Firefox build string: Mozilla/5.0 (Windows; U; Windows NT 6.1; WOW64; en-US; rv:1.9.3a5pre) Gecko/20100528 Minefield/3.7a5pre
