It was only December 09 when Google Chrome Extensions officially launched for its Chrome browser. Today, Chromium blog says that number is now past 3,000. And that is important because it is already pretty close to the well known browser for its add-one, Firefox.
The exact number of add-ons for Firefox is a greater than 11.5K. On its add-ons page, Mozilla notes that there have been more than 1.8 billion downloads. These numbers would blow away Chrome, obviously. But rate of growth in extension is very high compared to Firefox add-ons, if this continuous in long run Chrome will shy rocket is extension to unbeatable location.
Lets see what Firefox is going to do...

New Yahoo allows you to add your friends’ email addresses in Facebook to your Yahoo Contacts using Facebook Connect. In the Import Contact page of your Yahoo account, you can find select Facebook ( link importing from Gmail and Hotmail already exists). At once you authorize the connection with your Facebook credentials, all your friends’ email addresses from their Facebook profiles will be extracted and added to your Yahoo Contacts. Yahoo has the ability scan the imports and delete any duplicates, so there  wont be any double entry.



I waited for this for long time.
