If you’re anything like me and hate the annoying updates from really unimportant applications and you really don’t have the time to block them, new user script F.B. Purity has a quick and easy solution, getting rid of the irrelevant application updates and only keeping the core Facebook updates you’ve subscribed to.
According to the site,
Fluff Busting Purity is a Greasemonkey script that alters your facebook homepage to only show the most relevant information to you.
The script is compatible with Firefox, Google Chrome, Opera running on Windows, Mac or Linux or Apple Safari runing on Mac.
