The Facebook 'Like' button Firefox add-on is available through the Greasemonkey extension. This add-on makes the 'Like' button available to any web page via the added toolbar.

By clicking the 'Like' button on the toolbar, your friends will be able to see which websites you've liked even if they don't have an embedded 'Like' button on the original page. Allowing for more links to the Facebook network, this Facebook 'Like' button Firefox add-on is a helpful way for this social network to increase connections to external pages.
