Tapas RSS Button is a web extension for Firefox designed to improve user interaction with the Tapas.io platform, which specializes in webcomics and webnovels. This extension adds an 'RSS' button next to the existing 'Subscribe' buttons, allowing users to easily subscribe to series via RSS feeds. This functionality was previously missing, making it a valuable addition for avid readers and fans of the platform.

The extension operates with minimal permissions, only requiring access to data on Tapas.io pages to implement the RSS button feature. With this tool, users can now seamlessly access and manage their favorite webcomic and webnovel subscriptions in a more organized and efficient manner. The subscription-based model of the extension ensures continuous updates and support for users.
