Better Kemono/Coomer автор SirSalamandra

This extension aims to enhance the user experience on the Kemono and Coomer websites.

It includes the following features:
- Mark previously viewed posts as "seen";
- Add an audio player to posts that contain audio attachments.

This tool is still under development, so more features will be added in the future.

The extension is open-source. You can access the repository here: https://github.com/SirSalamandra/better-su
