[Discuss] sandboxing web browsers

It's no worse than the previously mentioned solution that required sudo
to switch to a dedicated browser user. If you are running a shared
system (neither of these solutions are likely the right fit), and you
don't want the regular user to be in the privileged 'docker' group, then
use a SetUID script (or sudo rule) that is restricted to launching the
specific container.

That's the recommended philosophy for using Docker in production
environments, but Docker also works perfectly well in a copy-on-change
model, just like a VM. Update the browser in-situ. (You can save the
state of the container if you want to be able to instantiate (or share)
clones of the updated container image.)
