Users of Firefox, Chrome and Safari browsers can download the +Like extension here. Search results will show a small button showing how many people have liked this page overall, and which of your friends have done so. Here’s a video detailing how +Like works.
The +Like extension was inspired by the recently introduced Google +1 functionality and built in just a couple of hours, according to developers. They used their own Crossrider framework to build the application. The +Like extension has an immediate advantage over Google’s +1, since it only requires the user to have a Facebook account. To use Google +1 a user needs to create or upgrade their Google Profile, begin marking sites as +1 and wait for their friends to do the same. Here’s a video of how Google +1 works.
