257470 - Closing one window closes ALL windows

Status: VERIFIED INCOMPLETE

(Firefox :: General, defect)

Description

[TGOS]

1. Visit the page of above
2. Open as many other Firefox browser windows as you want (these others may even
have multiple tabs inside; have them blank or load pages of your choice)
3. Close the window showing the page of above

Result:
*All* windows are gone and the Firefox process is gone as well, but no crash has
been reported

Expected result:
Just the one window close and the other ones stay open; or if an internal crash
takes place, it should be reported

Reproducible:
Always!

Additional info:
Even worse. I wanted to check if the page uses nasty JS code, so I opened
several windows showing me the source code of the single frames. When I closed
one of the src-code windows, I had the same effekt: It was all gone! And a
behavior like that can't be triggered by nasty JS code.
