I started using Firefox4 as soon as it was stable for release. I was pleased with features and speed, and it remembered my passwords (to the sites where that is practical - I know certain sites won't have passwords remembered for them). Then, suddenly, it stopped asking if I wanted to remember them. So I uninstalled and reinstalled. All was well again, until suddenly, once again, it's stopped asking me if I want it to remember passwords. What gives? I see about 6-7 passwords it has stored, but "remember passwords for sites" is checked, and it refuses to ask me. Why so temperamental?
