Multi-platform browser extensions are easier to write than ever, can have great authority to examine and alter HTTP requests and responses, and are shockingly easy to get listed on the official respective browser stores. In this talk Micah builds an over-powered, multi-platform extension.
In this talk, Micah gives an overview of how browser extensions work and the web-ext tool for creating extensions that work in both Google Chrome and Mozilla Firefox. He then shows how to debug and test extensions locally as well as how to package them up for distribution. The talk culminates with a real-time attempt to get an extension with an over-powered list of permissions listed on the Chrome Web Store and the Firefox Browser Add-ons Store.
