Like, recommend or share content with your friends from any site you visit with the Facebook Like plugin for Chrome.
You do not need to be logged in to Facebook to install this plugin, but to like, share or recommend a page you will need to log in to a current Facebook account, or create a new one. While the plugin is installed, it will display the total number of likes for the page you are viewing. To provide a personalized experience, Facebook will see some technical information such as the URL of the page you are on, your IP address and the date and time you visited the site. All information collected before you log into Facebook is anonymous or aggregated and will not identify you.
Facebook Like Button description:
Now you can like, share or recommend web pages, images, videos (html5 only) and audio (html5 only) on Facebook from any site you happen to be on, with the click of a button.
Once you've installed the plugin, you'll see a thumbs up icon in the top right corner of your Chrome browser. Liking a page is as easy as clicking on that button, which also displays the total number of likes associated with any website you are viewing.
You can also right click on any page to like, share or recommend content from the Facebook Like Button menu. If you choose to share content, you can add a comment and control who sees your post.
