huh, i don’t see the nav in FF but it works fine in IE and the load time was much faster. Check this though, I have the web developer extension for ff and when I clicked EDIT CSS to see if I could help you debug, and the sidebar popped up with your style sheet, VOILA, navbar appears. But a hard refresh and nothing again.
WHAT!? that doesn’t make any sense. This is going to drive me crazy, probably you first though. i’ll have to check it out after work though, good luck, i’ll check back later.
edit: if I click a link to one of your posts it also appears, when I click back it’s as if it was always there. So it’s something upon initial loading of the page, otherwise it works great.
