Hello, I would like to set up different profiles for different purposes. I tried creating a new profile with the profile manager. When I opened the new profile in a new window, it asked me to sign in. After signing in, it synced all my bookmarks and settings from the default profile. I then tried to edit the new profile by deleting the bookmarks that I don't need it to have. But this was then instantly synced to my default profile and I lost those bookmarks entirely. So, I don't understand how to make separate profiles that have separate settings and bookmarks and whatnot. I would like to have different profiles that are all attached to the same account and can be used on multiple devices, but i don't want them to sync with one another. That seems to completely defeat the purpose of having multiple profiles (they all end up exactly the same). I tried to get around this problem by creating an entirely new Firefox account, but then I get a message saying it will merge it's info with the account I just logged out of. This behavior makes no sense. Lets assume I have more than one user on a machine, and they each have their own account. If one logs off, and the other comes and logs in, now all their info gets lumped together? I also tried to have two Firefox windows open, with one signed in and one not, but they mirror each other. So I can't work in multiple profiles or accounts on the same machine at the same time. Back to the main question. I assume I am just using profiles wrong. How do I set it up so different profiles DO NOT sync with one another, but only with themselves across multiple devices.
