> problem is you can't sell them. I actually make a living selling browser extensions in the iOS and Mac App Store. Apple users are willing to pay. I used to sell my extension in the Chrome Web Store, until Google eliminated Chrome Web Store Payments (mentioned by another commenter). However, even with Google's payment system, my sales were extremely low; thus it wasn't worth my time to implement my own payment system in the Chrome Web Store. Apparently Firefox also used to have a payment system for add-ons but eliminated it. This is purely a choice by the browsers. Chrome and Firefox have chosen to demonetize extensions. Safari has chosen to monetize extensions.
