I was hoping to have different websites in my favourites bar, depending on whether i had the personal or work focus on, but it doesn't seem like you can do that. It's the same favourites for everything.
It's a good idea, but the haven't completely followed through on it
I figured it out, or rather the Apple video shows how. the stock profiles it creates do not allow this. You have to create a new profile and then there is a checkbox for use existing bookmarks or create new ones.
