On: Guide to Firefox Containers (2018)

Alternative low-effort solution that might break some websites (only issue I've run into so far is U2F based 2FA with Duo):

privacy.firstparty.isolate -> true (in about:config)

Effectively acts as a separate 'container' for every website.

The problem here comes in when you have things like SSO where many sites auth to Google, or AzureAD, etc.

With Continers I can login to the same site with mutiple accounts, for example one common use it where you have a Admin Account, and a Regular Account. You can use FireFox Containers to access the same site(s) using different accounts

I also do this with Amazon, so I can have my Work Amazon, and my personal Amazon separated with out having to use the "Change Account" feature which I find to be annoying

Yeah, I agree there are definitely usecases containers address that FPI doesn't. However, if your use case is just "I don't want Facebook and friends to track me across websites", you should give FPI a try!
