This is one of the more interesting bugreports I have seen. Basically:
A couple engaged to be married shared a computer. He used Firefox to visit a bunch of dating sites, being smart enough not to have the browser save his password. But Firefox did save the names of the sites it was told never to save the password for. She happened to stumble on this list had a big fight (According to her: sh*t hit the fan) and then they broke up. This is after 5 years of dating… Stupid guy… lucky girl (That she found out about this before tying the knot)
I guess FireFox should start promoting itself as: “The browser you can use to find out if your significant other is cheating on you”
Bugzilla Report: Bug 330884 (Read it, its interesting)
