The Facebook Twitter and Google +1 buttons module enable the Facebook Like/Share buttons, the Facebook Comment box, the Twitter Button and the Google +1 button in the node content of a Drupal website.
You will be able to load as a automatic plugin inside the content node or as a block in every part of the page template.
As plus will be installed even a facebook like box block.
We strongly suggest to create a facebook application and to use its app ID in the module's configuration. If you want to use the Like Box you need to set up a facebook page.
