Linkis TwitterAnywhere extension
Recently Linkis Project Team has released a browser extension TwitterAnywhere which replaces web ads with the latest posts from Twitter. It is totally free and requires no registration, email or any other personal information, which is great! After installing you can choose whether you want to keep track of the tweets from your feed (you have to login for that) or keep an eye on the most popular Twitter links according to your location and language (defined automatically).
TwitterAnywhere widgets have slick design and simple interface. There are a few functional buttons to make it possible to retweet or reply to someone’s tweet with no need to leave the web page you’re on. The add-on is compatible with all popular browsers as Chrome, Safari, Mozilla Firefox, Opera and Internet Explorer. You can check it out here
