I think you can get the profile from the browsercontext for a WebContents.

Could you please clarify this for me? The TabStrip takes a TabStripController
which is just an abstract class -- where can I get the WebContents from?

You are right. In which case I would prefer to keep this class clean of the
Profile and move as much of this logic into BrowserTabStripController. It can
take the request and asynchronously call back to the TabStrip with the results.

Done.
