Description

[Andrei Vaida [:avaida]]

Reproducible on: 
 * Nightly 36.0a1 (2014-11-11), 
 * Aurora 35.0a2 (2014-11-11), 
 * Firefox 34 Beta 8 (build1 / 20141110195804), 
 * Firefox 33.1 (20141106120505).
Affected platform(s): Windows 7 64-bit, Windows 8.1 64-bit.

STR:
1. Launch Firefox with a clean profile.
2. Enter full screen by pressing F11.
3. Click menu → Customize → click Title Bar from the bottom of the palette → click Exit Customize.
4. Exit full screen by pressing F11 again.

Expected result: The Title Bar *is not* visible while in full screen and visible once you exit full screen.

Actual result: The Title Bar is not visible in windowed mode although it appears as enabled in Customize.

Additional notes:
- This issue is not a recent regression, as I managed to replicate it all the way back to nightly builds from 2013.
