Which in fact /reduces/ overall system security. Starting a Docker 
container requires root. This means users who would not otherwise be 
doing things as root must now be root to start their browsers. Does 
anyone else see the problem inherent in this?

Actually, at least one does:

https://fosterelli.co/privilege-escalation-via-docker.html

That's not even beginning to touch on the problems with updating the 
browsers. Because one doesn't update applications in a Docker container; 
one updates the whole container. So, what happens to custom 
configurations and add-ons and bookmarks and passwords and auto-fill 
forms and so forth?

Less security and less convenience? Sign me up?

No thank you.
