Nice to have another potential user of Containers. Bear in mind that we
don't even have a prototype built into Firefox yet; Baku's addon Priv8 is a
great example though.

For now, you could experiment with it. As Baku's email said, there are
things like window.open() that do not work correctly. AppID is a B2G
concept that we hope to generalize for containers but that work hasn't
started yet. So, right not, we don't have anything for you to use. In the
future, yes, it seems like it could be a good model for your first party
isolation project.
