Facebook to Gray
Time spent on infinite-scroll websites such as Facebook may be a problem for some of us. Researching how to reduce this amount of time led me to an efficient solution: progressively turn the Facebook feed to black and white while the user scrolls.
That way, the user doesn’t feel the frustration from being blocked from using the website, the visual stimulation is simply slowly lowered as the interest for the time-consuming activity fades.
Facebook to Gray (beta) is a Firefox extension I developed, availaible on Firefox Add-ons.
