Does this make Firefox's containers unnecessary?

It depends on your usecase. Containers for me has nothing to do with this.

I use containers for sites like AWS where it doesn't understand the concept that I might want to switch regions or accounts but only in some tabs so that I can work on multiple parts of the network.

This obviously does nothing for that.

I use Containers to make sites have no stored memories of me. Most sites I open, a new, temporary container (extension required) for that visit, and swiftly deleted afterwards.

All my YouTube views are firmly disassociated from my account, so recommendations will only be impacted based on geographic data. News sites can't remember if I've been there before, other than using IP addresses.

There are other use cases for containers besides third party cookie isolation. If you want to have two separate sessions for a site, you'd still need containers.

Private windows can let you do that, so you don't really need containers.

Having containers means you don't have to log in every time, and you can have multiple sessions open in different tabs in the same window.

I have multiple sites like Github, Dropbox etc where I have multiple accounts I'd like to access separately. Typically private account vs work account, but also other scenarios.

Containers makes this a breeze.

In addition, at least Firefox only has a single private session. So if I open a site in one private window and another in a different one, they're in the same session, sharing cookies etc. Not so with different containers.

I find this a horrible usecase for me, I keep my password managers separate from my work provided one and my personal one. Containers don't solve this, and I use profiles, which I have to be thankful for MultiFirefox for fixing it. But only on MacOS.

I don't understand why fixing profiles isn't a priority, I find the usecase for them is completely different to containers which are awesome in a completely different way.

I’ve had a miserable time with Putting Google in a container and switching over SSO.
