Extension on Chrome

The latest news of Google Chrome has come. According to TechCruch, Google will announce their extension (like Firefox) to Chrome browser. This thing will be announced on a tech conference, Add-on-Con 09. Previously Chrome has support custom themes.
The Chrome OS has supported some extensions like it relates to Gmail but this browser is still lacking third-party extension. We know that the third-party extension has made the Firefox so popular and flexible yet multi function. About 2 weeks ago, Mr Google had been allowed the developers to upload their extensions but Chrome is still failure to use it.
However, a number of Chrome users have been successfully adding a lot of those extensions through a hack with no Google support. At the first stage, Chrome for Windows version will be able to use extensions. Finally TechCrunch has expected Google to unveil this rumor in this week.
