Then those should be loaded in in-process tabs, I would think.

That's not the plan.  The plan is to have a pool of processes used for 
tabs showing web pages (so multiple tabs can all be in the same process, 
in fact).  In-tab browser UI (e.g. about:addons) would continue to be in 
the browser process.

The latter, but that's not really relevant to your use case.

Yes.

 From an API standpoint, I believe the answer is yes (though under the 
hood there may be shared memory or whatnot involved).  But don't quote 
me on this.  ;)
