The current default means we process-switch for the first tab in a window, and potentially for other new tabs created (depends on specifics a bit).

The BrowserContentHandler passes in the default page to load, and we use that to determine the process type of the initial <browser> element here: https://searchfox.org/mozilla-central/rev/f53c09a22edc700ab1a9eaaf4da0f0dd9f11bff3/browser/components/tabbrowser/content/tabbrowser.js#493-500

From my testing, we're doing the right thing and choosing the privilegedabout type in the default case. So I think we're good here.
