I want to make an unattended installation of Firefox so when I open it, it will automatically sync with my account, and I don't need to type it again. This [Mozilla Wiki](https://wiki.mozilla.org/Installer:Command_Line_Arguments) gives you information about silent install, but it doesn't say anything about automatically adding my account. On the other hand, this [Mozilla Developer Network](https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options#User_Profile) page shows you how to use Firefox in CLI, but it only tells you how to create a profile, not adding an account. Do you know any way to solve this problem?
