Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b3) Gecko/20100805 Firefox/4.0b3 Haven't been able to reproduce consistently but I have seen it enough. I do have my laptop attached to an external monitor, but I have also seen this on my iMac as well Have seen this with authentication dialogs as well.

I am wondering if this may be related to tab candy since I am seeing this behavior on the trunk today: 1. Go into Tab candy and select one of my open windows. 2. Select the "red close" widget in the left hand corner of the window. 3. Observe the attached screenshot. It happens with every one of these windows. It may be that I had one window with 13 tabs open and somehow they got split into separate windows in TabCandy.

ftr, i got this today and haven't been using tab candy at all.

Marica can you tell me if you still have this issue, with the latest FF version. If yes please tell me the STR. I am asking you this because Tab group feature has been removed. Thanks

Thanks Marcia for your reply. Based on commnet 6 I will close this bug as Resolved:WFM. Please feel free to reopen it if you can reproduce this issue with the latest version of Firefox.
