Tangia Auto-Join watches Twitch chat for the message "Use !join to join the party." and automatically sends "!join" after a short delay, so you don't have to type it manually each round. Privacy: this extension does not use OAuth, the Twitch API, or any account login, and it does not collect, store, or transmit any data. It only reads chat text locally in the page and types "!join" into the normal chat box, exactly as a user would. Nothing leaves your browser.
