Page fade out effect

[Joe_Dean]

I'm looking for something for my forums when a member clicks 'logout', the page fades out and a popup displays asking them "Are you sure?"

Any such thing? :/

I also want it to work with Firefox. I don't really care about IE, as long as it works with Firefox.

I hope this helps,
