Create a profile using the profile manager
firefox -no-remote -profileManager
I have different profiles for different usages of Firefox, to keep them separate. Hopefully that increases my privacy a bit. For example I have separate profiles for general browsing, Twitter, WhatsApp, Facebook, Google Calendar and my bank website.
Launch Firefox with a profile with
firefox -no-remote -P "name_of_the_profile"
Set prefers colour scheme to dark
