Facebook has created an extension for the "like" in Google Chrome

Facebook Like Button is an extension officer for the browser that allows Google to include the "like" the social network of all the Web pages. It has the same button functions integrated on the sites and is available on the Chrome Web Store . Just be registered to Facebook to use them and the button appears in the contextual menu.
There has been no official announcement by Facebook, perhaps because the extension is scheduled for Firefox, Internet Explorer, etc..? However, there are three options available: Facebook Like Button, in addition to "like" integrated "recommend" and "share". That allows to send a link to friends or publish it in your wall.

Beware, though, because installing Facebook Like Button for Google Chrome s'accettano implicitly the terms of use and privacy policy of social networks . In particular, the extension will be recovered in the browser history and IP address of the user : the data remain anonymous, login to Facebook.
