Sorry, my english is not so good.

With sync, there is no master. All selected data is shared with all members of the sync.

Thank you FredMcD. I wanted some common and some unique bookmarks , addons, etc on my firefoxes. It seems not posible yet on sync. I guess I'll just do it manuallly.

Bookmarks: Set up a folder called 'Work.' This will separate work links and still be available in case you need them.

hi there,

  I am using same Mozilla account in my IOS device and window. I have saved lots of password in my IOS firefox but when I do sync on window , all saved log in is not coming up.  What should I do to have same number of saved login in both device with same account ?
