Digital Trends – Without a mention last month, Facebook released a plugin in early July to provide a built-in graphical button and pop-up menu functions for sharing a page on Facebook. After adding the plugin, users can click the thumbs up button and a pop-up window appears which loads the Facebook Like button widget. Users can also right click on any webpage to bring up a menu for liking, recommending or sharing the content. There isnât an option for Facebookâs Send button though, a function that allows users to send content to any email address as well as people on the Facebook friendâs list. A user doesnât need to be logged into Facebook to get the button to work and thereâs minimal setup to get started.
