File this under: Bizarre. Firefox Bug 330884 brings us this sordid tale:

Basically, we share one computer but under separate Windows XP user accounts. We both use Mozilla Firefox — well, he used to use it more than I do but now we don’t really use it. The privacy flaw is this: when he went to log-in under his dating sites (jdate.com, swinglifestyle.com, adultfriendfinder.com, etc.), Mozilla promptly asks whether or not he’d like Firefox to save the passwords for him. He chose never, obviously. However, when he logged off his user account, and I logged onto my Windows XP account X amount of days later…I went into the Password Manager to change the saved password option from Never to Always and that’s when I saw all these other sites that had been selected as “Never Save Password.” Of course, those were sites I had never visited or could ever dream of visiting.

The moral of the story is you should use a different application for extra-marital browsing. Maybe something light like K-Meleon or just running Firefox from a thumb drive? Just a thought.

And yes, I do know that this is not a valid bug, she screwed up the set up of user accounts under XP.
