Steps to reproduce:
Under Windows, enable Aero and set the desktop background to black. Open an email with an attachment in Thunderbird 11.0.1 running the default theme.
I couldn't read the attachment's file name because the text was the same color as the background.
I should have been able to read the text because the text should have been a different color than the background.

This patch removes the now needless -moz-win-borderless-glass appearance for the messageWindow and gives the attachmentBar the same color as in messengerWindow. Also styled the status-bar like in messengerWindow.

Comparison before and after patch
This screenshot shows the attachment bars of standalone window and main window. On top before the patch, below with patch. The only difference is the color of the bar. With patch both have the same color, without patch not.

Patch for aurora and beta
In case this patch should land on aurora or beta I've added a version without the status-bar color change for Australis.

I don't know if this is the same as the original reporter's problem, but it certainly does what it says in the patch description, so ui-r=me.
And the code seems fine, too, so r=me as well.
