Hehe, my firefox tabs have always worked this way, and in fact, to me, the most annoy thing about IE7/8's tabs is, only the active tab has the close button !! I was SO frustrated. Tongue Out

Thats why I really like this feature of VS2010 Smiley

and, talking about the tab order, maybe you can try this in 2010:

 

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\General]

"DocumentDockPreference"=dword:00000001
