Enable Strict Enhanced Tracking Protection setting, this turns on Dynamic First Party Isolation which is the native version of what Temporary Containers is aiming to do.

I believe this is privacy.firstparty.isolate in about:config, if you want to do this manually

That's not for the Dynamic version as far as I'm aware.

Is there a way to enable the dynamic version via about:config to your knowledge?
