Nice tips. I would add: embrace tab containers (https://support.mozilla.org/fr/kb/utiliser-conteneurs-firefox https://support.mozilla.org/fr/kb/utiliser-conteneurs-firefo...), especially if you love chrome profiles. They do half of what profiles do: they isolate cache, cookies, sessions, etc. But they do so in a very light manner and fast manner. The UI is better too. So for things that don't need getting different settings or extensions and so on, containers are the way to go.
