Hi, I played around with your site and code a little bit (hope this was ok :-). What I discovered was that FF (and others) seems to have problems with setting (or animating) the width of an empty div via css. Adding a $('.main_content').html(" "); before your open animation will do the trick.
This is independent of loading the content in the background. Even then you might have an empty div at the start of the animation. So place a space in your main content and overwrite it once the page has loaded. by(e) Stephan 2009/2/4 re5et <zerodex...@chello.at>: > > btw, I fixed the "Could not get the display property.
