How I use Firefox

• 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

  You can update the style used by Firefox by going to about:config and adding a new property ui.systemUsesDarkTheme of integer type with value 1.

From StackOverflow

• Make everything dark with https://github.com/SrKomodo/shadowfox-updater

• Might have to set Gnome theme to dark with gsettings set org.gnome.desktop.interface gtk-theme

• Reduce Firefox’s memory consumption

Issues

There is a very annoying bug whereby the volume of a video, set with pulseaudio, resets on interactions such as forward, rewind, and various others. See https://bugzilla.mozilla.org/show_bug.cgi?id=1422637.
