If you are someone who you do not like Facebook and navigation in various web pages asking you to login to the Facebook account to comment on a post or somewhere on the page you can take several widgets that encourage you to share content ...
I present Facebook Blocker, An extension for Firefox, Chrome and Safari which enables you block all traces of Facebook on any web page, such as buttons of "Like" or "Like" to become a fan widgets, or buttons to share.
It is special for those people who do not like Facebook and do not want to see traces of that network on the web.
