Chrome Extension Notification Demo Not Popping Up

I am working on a Chrome Extension, which will have a pop up in it, however when I go to use the Notifications Demo App and install it in Chrome it doesn't display any notificat开发者_StackOverflow中文版ions. I don't know if there is something wrong with the sample app which is here : enter link description here or that it's become outdated and thus it's a permissions problem. Any help would be appreciated as previous questions I found don't seem to have a notification problem in regards to extensions, but instead to putting them on their blog or the likes.

Thanks,

I encountered a similar problem. It's a bug in Chrome: http://code.google.com/p/chromium/issues/detail?id=77682

Going into chrome://chrome/settings > Content Settings > Notifications and selecting "Allow all sites to show desktop notifications" is the only fix I can recommend right now.
