One item that Facebook will never allow is the “don’t like”, because of its negative connotation. Facebook, like all other social networks, must have a positive environment in order to prevent abuse for it’s members.
To add this button you have to install (unless you use them already), the browser Firefox or Google Chrome.
Now simply install the extension Facebook Dislike (link for Firefox – link to chrome) and the extension options to choose the English language.
Each time you click "don’t like" you’ll see the image with your thumb down and the words "don’t like" – if you did not install the extension you will instead have a comment generated with the words "I do not like(http://www.facebook.com/group.php?gid=188316883805) "(link to the group extension)
