How to sync home/work Firefox

Is there any way to keep 2 Firefox browser synced up? Specifically Bookmarks and Extensions? Is there an extension that handles this? I haven't had any luck finding one.

Well...Nevermind...I just looked "harder" and found at least a Bookmarks syncer. I guess this will do.

Bookmark Synchronizer is great, but you need an FTP site as a segway. Don't know about the Extension thing, though.

i can use my works ftp

What I'd really like is a Profile syncer so I can just seemlessly go between the two. Maybe I should just get a laptop for work and home...that would probably be easiest :)
