insert youtube but sidebar got pushed down

ailing, I’ve just visited your blog (via FF, IE and Opera) and it seems as if you had resolved your problem.
As I currently face a similar problem – blog with youtube works perfectly with IE and Opera, but not with FF, sidebar and layout get smashed – I’m impatient to know how you did it? Or anyone else an idea?

search forums for “sidebar drops” and related terms. This comes up all the time.

Thanks Adam, I’ll check that. I can’t see the wood for the trees sometimes…
