I think this process is unusual but the result is critical. If you go to full screen mode when you are in Private Browsing Mode, the display will be broken if you use the short cut to stop Private Browsing Mode. It results in only the Firefox window being displayed. The Firefox menu and Dock disappear. This does not happen when if you are not in Private Browsing Mode first.

Reproducible: Always

Steps to Reproduce:
1.Start the Private Browsing mode
2.Start the Full Screen Mode
3.Stop the Private Browsing Mode from keyboard short cut (command+shift+P)
Actual Results:  
Display will be broken.

WFM with Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.3a1pre) Gecko/20100108 Minefield/3.7a1pre (.NET CLR 3.5.30729) ID:20100108043818
Is this with 3.7 or 3.6?

It occurs with 3.7 and 3.6. It might occur only on Mac.

Similar phenomenon occurs with Firefox 3.6 RC1 and Minefield 3.7a1pre on Windows XP Professional.

Sorry, I was wrong.
In the full screen mode, it does not display the menu bar.

Can someone from the Session Restore team please confirm if this is the same issue to bug 500150?

Looks like it. Though comment #1 saying WFM on Windows is suspicious. That would mean we fixed it without knowing it.

This is going to be due to the reuse of the window. We'll probably need to do some checking if the window is in full screen mode & take it out first. Besides these 2 bugs, I haven't seen anything about session restore & full screen mode before. We should probably open a new bug for general support & make sure this particular problem is fixed as well.

I'll look into this today.

This is no longer valid in the new per window private browsing.
Closing the bug.
