Complementary to this, one can use the Temporary Containers addon to get isolation of e.g. cookies. I've set it up to run one container per domain, and it works really well. I hope they merge this into Firefox at some point.

I ended up having to disable my containers plugin due to syncing issues and later...CPU usage. It wasnt terrible on a better processor (like 1-2 cores 50-100% consistent usage) but on my old core2duo thinkpad it was basically useless. And on any laptop that was unacceptable.

I like the idea of containers, and will probably revisit periodically to see if whatever was fubar on my account is resolved (theres none/if any logging, so its hard to really dig in)

How did you set it up to use one container per domain?

I'm using Temporary Containers, but if I visit `somedomain.com`, close it, and come back later, I get a new temporary container.

First Party Isolation is the native version of this (AKA Total Cookie Protection). Set Enhanced Tracking Protection to Strict to enable it.
