Tried that 3 times - no crash. But the music stuttered for a few seconds while the bookmarks window came up.
Also, after the bookmarks window comes up once, there are no symptoms from opening it again (until Firefox is restarted).
For my part, I don't mind the crash since I can avoid it; however, if it is useful for your work, I will continue to do what you ask.
