Fluff Busting Purity


Fluff Busting Purity, or FB Purity for short is a web browser extension designed to customize the Facebook website's user interface and add extra functionality. Developed by Steve Fernandez, a UK-based programmer, it was first released in 2009 as a Greasemonkey script, as donationware. It is available for Firefox, Google Chrome, Microsoft Edge, Safari, Opera, Brave and the Maxthon Cloud Browser.
In February 2012, Fernandez was banned from Facebook, although he was allowed back two weeks later. In April, Facebook blocked links to his site, with an error message saying the site was "spammy or abusive", a generic error message given for any site that they deem to have violated their terms and conditions for any reason.
In December 2012, the company both objected to the name "Facebook Purity", and claimed that its development violates the site's Terms of Service. In response to this perceived violation, the company told Fernandez he was unauthorized to access Facebook, which he described at the time as potentially the "end of the road" for the script's development.. However, the add-on continues to be maintained and updated by the author, which is clear from the regular version releases on the FB Purity website, and other official browser specific download pages of the FB Purity extension:
