I just updated the k2 theme used on my website, and after a great deal of work I think I've got the custom css working again.  At least, on Safari and Chrome and Opera.  The problem is, it's not working on Firefox.  And I have no clue why.  Using the default theme, the right sidebar shows up at the bottom rather than on the right, and pages which should have no sidebar have the main content pushed over to the right.  These problems do not occur in Webkit based browsers, nor do they occur in Firefox using the "Inverted" theme.  But I haven't added anything positional, as far as I can tell, to the default theme.  So I have no idea what's going on.  

If someone with more CSS experience than me could please take a look at http://dreamhart.org in firefox and figure out what's going on, I'd really appreciate it.  I'm completely stumped.
