"Show Password" button in Firefox...

So, Firefox is a great browser. Use it pretty much all day every day, on and off. I saw a headline for a story on Digg the other day that I didn't really have time to check out properly but I think it was referring to this:



I can't believe that this feature to "Show Password" should be even in a web browser - anyone know why it is?? I'm not really (*that*) paranoid, but anyone who ever uses my computer or is left alone with it could easily in about 3 clicks get passwords to all my regularly visited stuff. I'm not saying I don't realise that if I've ever typed my password in (or not!) anywhere and that computer is left alone with someone who knows what they're doing (or can use google...) they wouldn't discover my password anyway, but let's say I'm having a party and my computer is freely available to people using Spotify then I'm sure there will be a bunch of randoms casually using my computer that could if they so wished view my password a little too easily.

Anyhoo, here's how to get rid of it.
