Its a small thing, but its quite annoying... Reproducible: Always Steps to Reproduce: 1. Closed all windows in program. 2. Restarted 3. Checked preferences menus etc. Actual Results: Nothing was fixed. Expected Results: Mozilla Firebird should have shown only the windows that I actually had open when using the Exposé feature.

I have noticed for some time that when I alt-~ through the open windows in Firebird there is a hidden window of some kind: the other windows title bars will dim, but there is no apparent window. It seems that this is the same problem, now revealed more easily using Expose.

Confirming. See also Bug 223545, this bug's twin in Mozilla Proper, and Bug 150028, the original Hidden Window on Mac bug (featuring the option-minimize and command-~ appearances of the elusive window)

the hidden window gets the menubar functional again incomplete workaround of Bug 21296 and keeps the firefox open if no window is visibly open.

fixing this would make firefox on mac look much cleaner.

Can confirm this behavior using Mac OS X 10.3 and Firefox 0.9.1 Its probably the most annoying cosmetic bug I've noticed, and definetly needs fixing before 1.0 Interesting, it doesn't occur when I am running in dual screen mode with my CRT, only when I am running using my Powerbook's LCD screen by itself.

To stop a window from being affected by Exposé, you should be able to adapt this code: http:// www.cocoabuilder.com/archive/message/2004/2/12/96974 However, the hidden window will still be noticeable when using command-tilde to cycle windows.

The CGSTagSticky hack doesn't block the movement of the window during Exposé's "Show Windows", only during "Show Desktop".

I do *not* witness this behavior using Firefox 0.9.1 under OS X 10.3.4.

(In reply to comment #11) > I do *not* witness this behavior using Firefox 0.9.1 under OS X 10.3.4. I have the same setup and witness this behavior when pressing both F9 and F10. So I don't think this has been fixed.

It is fixed now (see bug 223545).
