I think you may need this in a different file since I don't think browserless
panels should include a file that mostly exists to support the browser.

   if (zoom == content::PAGE_ZOOM_RESET) {
     host->SetZoomLevel(0);
     content::RecordAction(UserMetricsAction("ZoomNormal"));
     return;
   }

   double default_zoom_level =
-      browser->profile()->GetPrefs()->GetDouble(prefs::kDefaultZoomLevel);
+      profile->GetPrefs()->GetDouble(prefs::kDefaultZoomLevel);
 
   // Generate a vector of zoom levels from an array of known presets along with
   // the default level added if necessary.
