Google +1 Plus One Extension

Google '+1' Sharing Button is yet another attempt to make Google more social.
It's Google's version of the Facebook "likes", a simple feature that's very powerful because it's part of a social network.
+1 is the digital shorthand for 'this is pretty cool.'
To recommend something, all you have to do is click +1 on a webpage.

IMPORTANT : "RESTART browser after installing the extension."
