Please use Services.vc.compare() here as well.

As with the other review, this should be:

if (subscription && !(subscription.url in FilterStorage.knownSubscriptions))

     {
       subscription.disabled = true;
       FilterStorage.addSubscription(subscription);
       if (subscription instanceof DownloadableSubscription && !subscription.lastDownload)
         Synchronizer.execute(subscription);
     }
   }
 
   if (!addSubscription && !addAcceptable)
     return;
