About PurpleAdblock

PurpleAdblock is an open-source adblocker for Twitch that uses server-side signature handling. It is available for Firefox, Google Chrome, and as a user script.

The project recommends not using it alongside other Twitch adblockers or scripts with the same purpose, and suggests using a general adblocker such as uBlock Origin. Manual development installs require additional steps, and a temporary Firefox install is removed when the browser closes.
