This extension enhances the facebook site with automatic notifications from your “News Feed”. We’ve put special attention into maintaining the look and feel of facebook.

This extension has next features:

1. Notifies about new stories in news feed page (checks for new story every X seconds). If there is number of new stories, notifies about them in one message in their original order.
2. Ads does not referred as new stories, and does not included in notification pop-up
3. The stories in notification pop-up looks just like the original ones, except the fact that they are narrower. This includes the original images, and original style.
4. All links in the notification window are redirected to the main bubble window. If bubble window minimized, it is restored. Executable scripts (i.e.: on-click scripts) are also redirected.
5. By clicking somewhere in notification window, the notification closes and bubble window restored, if it was minimized.
6. Optimized to work on IE6 and IE7

I like to hear ideas and advises for this extension. If you have some, then please post them in forum.

I would like to notice that Facebook changing its appearance pretty often. So, sometimes, after such change, some feature may not work. In that case I will be glad if you will put my mind on these problems and post them in forums.
