i.e,

after i've initially synced, i'm wondering if like chronosync does...... say I move some unsorted bookmark links into a bookmark folder i created, during my next sync will firefox make two copies of this bookmark link now on each device? let me try and explain - so one will be added into that folder on the other device because it's missing (not yet sorted into the folder) but will the bookmark also be added back to the unsorted tabs of the device on which i moved it originally, because on the other machine the bookmark will be present because i haven't sorted yet. so in the essence i now have two copies of the link on each device which is not what i want. hope i'm making sense, i'm confused after typing this. thanks in advance.
