So I frequently install firefox on different desktop devices and it’s a hassle to set up and configure all the privacy settings and extensions every time I install it on a new device.

Obviously using a FF account and sync would be the easiest way to set it up quickly, however the I don’t want to keep my account logged in on every device since some of the devices aren’t mine.

Having said that, is it possible for me to create a new sync account and configure it the way I want to; then log in on a new install, sync the config, logout, but retain my configuration there; essentially using the account to bootstrap config new firefox installations?
