Here's a policy patch for chrome/chromium. I don't expect this to be accepted
as-is, Chris tell me what you would like in a patch for inclusion.
Last time I posted this someone else said they had a good patch that they were
going to submit but that never happened.

I didn't really look much farther than here. It seems like this
terminal access is more of a potential to dontaudit, since it is a
sandbox. I'm not clear why we can't simply have
userdom_use_user_terminals(chrome_sandbox_t) in the TE rules, rather
than passing the same type all around.
Beyond that, this simply won't fly because all the seemingly conflicting
types. A user might think, "what does mozilla have to do with chrome? I
don't even have mozilla installed!" For this to work, we'd have to go
down a generic browser policy, with correspondingly generic type names.
I'm not opposed to this, but that'd be the first step.
