I've used Firefox as my primary browser since the "Quantum" in 2017. Chrome still feels snappier, but Firefox's Container Tabs is hard for me to imagine losing.

That's not what container tabs are. Think of it as isolated environments for groups of sites. You can even set it up so that each new link opens in a new environment, without any cookies, etc.
