Experimenting with this addon: Firefox Multi-Account Containers.

I don’t really even know what I want to do with it tbh.

Firefox Multi-Account Containers lets you keep parts of your online life separated into color-coded tabs that preserve your privacy.

Cookies are separated by container, allowing you to use the web with multiple identities or accounts simultaneously.

It’s more of just a hunch to me at this point. I know it’s important, though I don’t fathom really the practical day-to-day usage. One way to find out, I suppose!
