Good that they are integrating that into the main browser.
For me the big use case is having different Google accounts active in one window. Work and private. And when I was doing freelance projects, I sometimes had 3 or 4 different Google accounts active. Plus assorted stuff tied to those accounts. Using different colors for each makes it easy to tell apart the tabs.
Another use case is if you are testing the same app for different customers with different credentials. I do this a lot and I have dedicated containers for each customer so I can easily switch with out having to log out and in a lot.
And of course some companies that can't be trusted with cookies, like Facebook, get isolated. I open that container less and less these days. But I still check every few months. I also keep my bank's website in its own container just on principle.
If seems this should make obsolete the setup of having a separate computer (e.g., old laptop) to isolate Facebook properties, or am I missing something where a separate machine would be advantageous?
(I avoid FB like the plague but may need to use it for some biz uses where they effectively host too large a share of the intended market)
This has been one of my use cases for the Multi-Account Containers extension for some time now. It's actually such a motivating use case that one of Firefox explorations into a "simpler" focused UX alternative to the Multi-Account Container extension is called "Facebook Container" and does only that, isolate Facebook, specifically into its own Container.
As noted, it can't defeat all forms of device fingerprinting, but it does defeat cookie tracking.
Depends. Either you need to guard against e.g. fingerprinting the GPU, in which case you still need a separate machine, or you only need simple separation of cookies and the like, in which case you never needed that and could just use separate browser profiles. But yeah, I think in the latter case containers should work, though if it matters you should double check what exactly they do and don't separate.
