Let’s say I use Manage Bookmarks to rearrange my bookmarks into different folders & also delete a lot of old bookmarks on my desktop computer. Are all the changes I just made immediately reflected in my Mozilla account if Sync is on? My (vague) understanding is that the Sync configuration in my Mozilla account acts as a master configuration; does that mean the Mozilla account configuration will overwrite the configuration on my laptop when it Syncs? Or will the laptop’s configuration instead be combined with the desktop’s configuration in the Mozilla account, thereby creating duplicate bookmarks in different folders & recreating all the old bookmarks I so painstakingly removed?
