Here's what it does:
- Once every 4 hours, it scans headlines on homepages of NYTimes, Fox News, Huffington Post, CNN and Washington Post
- If there is a headline that contains the same word on 2 or more of the sites (excluding articles like "a", "the" and pronouns), it uses some type of fuzzy-filtering to grey out all appearances of all versions of this headline on all social networks, especially twitter.
It must work in Firefox 57+, and ideally it would work in other browsers as well (via WebExtensions). Released under some open source license.
