does this need a virtual destructor?

yep according to the style guide, i'll add one.

  public:
   // Notifies that a plugin process has started.
-  virtual void PluginProcessStarted(const string16& plugin_name) = 0;
+  virtual void PluginProcessStarted(const string16& plugin_name) {}
 };
 
 }  // namespace content
