Different Sync Items between different PCs
I have 3 systems that I want to use Firefox Sync on.
PC: everything. Laptop 1: everything but addons and settings. Laptop 2: bookmarks only.
I cannot make the sync settings persistent. After every sync all system sync settings reverted to the latest sync system. For example, set sync setting for laptop 2, then after sync started on 3 machines all 3 only sync bookmarks now; set sync for laptop 1, then after sync everything is on Laptop 2. Chrome did this really well so I can isolate some sync features on certain machines.
How can I do this on Firefox?
