I use firefox account on my devices but I have personal bookmarks in a subfolder on my bookmark bar (Folder marked personal) One of the devices I want to sync other bookmarks to is my work PC but I do not want the personal folder to sync up to the work PC, There does not appear to be any way to mark folders as Do Not sync, Is this a function that is likely to be added or am i stuck having personal/private links being sent up to work which in some situations could cause me problems at work - or do i need to just store these personal links outside of Firefox for privacy?
