OK, this bug is definitely back. Reproduction method as in OP, only it's not even necessary to start ubuntu-bug in the terminal, you just have to alt-tab back to firefox, and it breaks.
Marking regression-update, since I'm fairly certain it was OK in freshly released oneiric. Setting Confirmed (if I'm allowed to).
