I'm thinking of getting a new computer (it will be a mac; I'm also on mac osx now) and I'm trying to determine if Firefox sync will allow me to setup a new computer with my old computer's bookmarks, passwords etc. (all the items i ticked in sync preferences) on the new computer? Basically, will it just sync my old bookmarks and passwords to my fresh computer and fresh copy of Firefox once I sign into my sync account?

Thanks for your help.
