Firefox issue should be fixed. Gecko is weird about some CSS rules, it also renders Helvetica Neue way too thin. I've subbed in Arial for FF users. Sorry about that.
As for Honeycomb people, I'm sorry but Honeycomb behaves very odd--reporting itself NOT as Android. this is a well documented problem. I just don't want to write a fix for it. It behaves fine on the iPad/iPhone and any mobile Android browser so I assume Honeycomb will catch up soon.
