I made ZuckFeedsBGone
TL;DR: Self-promo for a Firefox extension I made that helps me spend less time on Facebook and Instagram.
I've wasted countless hours scrolling through the Facebook news feed (and Instagram) over the years, so I decided to make a browser extension that nips this activity in the bud.
So far, it's been effective. I spend much less idle time on social media after the week or so I've had it installed.
Following Jame Clear's guidelines of "Start small" and "Make it easy", this extension simply gives you the option to remove certain elements of the Facebook and Instagram websites, for example, the Facebook news feed and stories; and the Instagram explore page and suggestions.
Hope it can help others too, feedback welcome!
Free, and open source.

If you want to charge for it or add premium features, take a look at my project https://extensionpay.com. It makes it really easy to take payments in browser extensions :)
