-- Information about the crash:
I can repeat this crash every time in RC (4.3.90).
Open a firefox windows, open download and any other window from firefox (downthemall?), open more windows to cause the firefox windows get grouped. Then just select one window from the group ant close... should crash.

The crash can be reproduced every time.
