Hi! I just set Firefox Sync and only one device is actually syncing. Initially all items were checked like in the first figure. Then I unchecked everything but bookmarks like in the second figure. Is that sufficient to say that now my Firefox Sync only contains bookmarks? In the next days I will connect other devices, but I do not want that these other devices get (and also share) preferences, tabs, passwords... (for example, sharing preferences results in having the same initial page, that I do not want) I read that all Firefox Sync data are erased (from the server) if I change password. In order to achieve my aim, is it better to change my password too? Thanks for the answers!
