Status: RESOLVED WORKSFORME

(Firefox :: Shell Integration, defect)

Description

[Gene Z. Ragan]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/164 (KHTML, like Gecko) Safari/164
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; rv:1.7.3) Gecko/20041001 Firefox/0.10.1

Lauch Firefox.  If you hit F9 on OSX to use Expose, you see a small window appear with no title in the title 
bar and no content in the window.  This window is owned by Firefox and is usually at a large negative 
origin.  Using this approach with an "offscreen" window is a bad idea as Expose will show it and, as 
monitors support increasingly large resolutions, multiple high resolution displays with high DPI settings 
may expose these "hidden" windows.

Reproducible: Always
Steps to Reproduce:
1.Launch Firefox
2.Hit F9
3.See tiny window appear

Actual Results:  
Tiny window appeared at the top left of the Expose window display.

Expected Results:  
No tiny window should appear.

In theory that should have been fixed by bug 223545 in builds after 20040924.
(Or is 20041001 0.10.1 how 20040913+patch announces itself?)

Works for me.
This bug was fixed after the 1.0 PR release. If you still have this problem with
a recent nightly build, reopen this bug.
