Works perfectly! Having 40-50 tabs restored on startup and having 5-10 master password windows poping up over previous popup with half-entered password is major annoyance. This addon do what had to be done in the first place by Firefox team.
If I'm not mistaken in FF4 the bug is fixed already and this addon is not needed.
