Status: RESOLVED DUPLICATE of bug 263160

(Firefox :: General, defect)

Description

[erik red]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20061208 Firefox/2.0.0.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20061208 Firefox/2.0.0.1

See below.

Reproducible: Always

Steps to Reproduce:
1. load a session of tabs (about 40 sites in about 10 windows)

2. just go about normal browsing business, and pretty soon some tab will
   become/create a disembodied window with title "Untitled". The
   original tab often becomes an all white pane after the disembodiment
   has taken place.

3. especially prone web sites are www.marketwatch.com and
   finance.yahoo.com, in particular when looking at portfolios. 

4. The disembodied window sometimes contains the whole web page, and
   sometimes there is a multitude of disembodied windows, each
   containing a part (maybe a subframe?) of the original web page (tab).
   The disembodiment can *sometimes* be undone by reloading the
   orginating tab, but only very unreliably.

5. The disembodied windows never contain the firefox toolbars, they
   simply contain an image of the original web page or part thereof. It
   is often possible to follow hyperlinks etc in the disembodied window.

6. If I iconify the Untitled disembodied window,they will pop up
   again at seemingly random times.

7. The window manager cannot delete the disembodied windows.

8. The problem has been in existence for a long time, I think back
   to firefox 1.0.

9. The problem is not dependent on the window manager in use. I tried to
   switch between twm/fvwm/mwm/openbox while keeping firefox running,
   and the disembodied windows are still there.

10. Only firefox is creating these spurious windows, no other application.

11. This problem is driving me crazy. I just had 15 Untitled windows
    popping op randomly, and I can't access the original web pages.

12. Please help!

Actual Results:

Expected Results:  
Firefox should not create disembodied windows
