I usually use xmarks but wanted to try the FF sync as its one less adon i need but i have some questions. If i have 2 comps with completely different bookmarks which takes precedence ? If i do a fresh install of FF on another comp and then log-on to my sync account will the empty (well almost empty as default FF has a few bookmarks on it) erase all the bookmarks from the upload server and then wipe everything from my other computers ? I suppose im confused as you can not specify if you want to upload a specific computers data or download it from the server or maybe even merge it (although id never need to merge them) . Just seems to be an absolute lack of control here :-/ Thx all.
