So, recently the title bar in Firefox 3.6.4 looks different in my Windows 7, and has an extra button for switching windows between multiple monitors. It kinda looks like Vista, I think. This change seems to come and go, and it only is there in one of the several Firefox windows I have open... the rest are normal. Also, when it gets bogged down it reverts, and when it catches up, the new look returns... I want to make sure this has to do with an update or something, and not malware, because it's pretty weird and the inconsistency is alarming. == This happened == Just once or twice == Last week
