[ale] OT: FF3.x masquerading as IE? on WinBlowz

[hscast at charter.net (Scott Castaline)]

There used to be a plugin or extension that would allow FF to masquerade 
as IE6. Does any6one know if that still exists and will it also "fool" 
the site into believing that you're a WinBlowz machine. I haven't had a 
need for this in a while, But my significant other, now a loyal Linux 
user, has a need to access a site that only works for a PC that is 
running FF or IE on either Windows or OSX only no Penguins allowed.
