could you use ExtensionRegistry instead? we're trying to reduce the usage of
ExtensionService.

const extensions::Extension* extension =
    extensions::ExtensionRegistry::Get(web_contents->GetBrowserContext())->
        enabled_extensions()->GetExtensionOrAppByURL(url);

consider using ternary-if for |origin|, but, up to you.
