Hides Facebook posts that contain user-defined keywords and/or phrases.
This extension filters or highlights any Facebook post that contains specific whole words within the text or link title of a post.
There is no technique employed here to capture multiple forms of any word, so if you want to block/highlight anything containing "die". you would have to set your blocker to something like "die;dies;died".
This application uses regular expressions. As such, using the example above, if you don't care about also capturing words like "remedies", you could use "\S*die\S*".
