These methods (at least Accept(), Deny(), and Closing()) should be defined in
BubbleDelegate.

These are all callbacks from the UI. What's the advantage of adding them
to the base class if no part of the bubble API will call them?

+
+  // Pass along to the BubbleUI.
+  Browser* browser();
+  const std::vector<PermissionBubbleRequest*>& requests();
+  const std::vector<bool>& accept_states();

[please use gerrit instead, 2015/08/05 18:05:25]

These methods are used only in BuildBubbleUI(), so they should not be public.
Send this information to PermissionBubbleView::Create() somehow.

[hcarmona, 2015/08/05 18:43:47]

Only this class knows about it, so it shouldn't be a problem.

+ private:
+  PermissionBubbleManager* manager_;
+  PermissionBubbleView::Factory view_factory_;
+};

  DISALLOW_COPY_AND_ASSIGN(PermissionBubbleDelegate);

[hcarmona, 2015/08/06 17:43:44]

Done.
