[Bug 1044742] [NEW] Firefox titlebar disappears when restoring from minimized state

[Alex Cabal]

Public bug reported:

When minimizing Firefox and restoring it by clicking a link in
Thunderbird, the FIrefox window restores, but without the titlebar and
window controls.  Note that this is NOT related to the F11 fullscreen
view.

Occurs in Ubuntu 12.04 64bit, Gnome Classic, AMD HD 4500 video card,
fglrx 12.6

To reproduce:
1. Open a Firefox window and minimize it.
2. Open Thunderbird and click on a link in an email.
3. Observe the bug: the Firefox window maximizes with a new tab for the opened URL, but it's missing the titlebar and window controls.

Minimizing this broken window by clicking on the taskbar and restoring
it again brings back the titlebar.
