Facebook is a social networking website and it is being very popular to everyone. But the problem Facebook is having now, you have to visit Facebook website to access. On the other hand, look at Google, it supports its social network application (OpenSocials) initiative which will let people develop applications that can run on any website.

Recently Facebook has taken another step to becoming the defector operating system of the web 2.0 world. Facebook recently updated and releasing a JavaScript client library which enables you to add Facebook application to any site. Now you can use Facebook as a toolbar for Internet Explorer and Firefox.

Wei Zhu from Facebook explains the benefits:

Since the library does not require any server-side code on your server, you can now create a Facebook application that can be hosted on any web site that serves static HTML. An application that uses this client library should be registered as an iframe type. This applies to either iframe Facebook apps that users access through the Facebook web site or apps that users access directly on the app’s own web sites. Almost all Facebook APIs are supported.

I have not seen yet anyone to use Facebook as a toolbar into any browser. But I think it is a great move by Facebook and it will enable Facebook to get competitive advantage.
