Ruby - Oshi no Ko 🌟(Dynamic theme) von Archer_W 🏹

Just open tabs, bro. You’re only one click —or tab— away from witnessing how light or darkness bursts in and changes everything at the most unexpected moment.

Solo abre pestañas, hermano. Estás a un solo clic —o pestaña— de presenciar cómo la luz o la oscuridad irrumpen y transforman todo en el momento más inesperado.

This add-on only changes the background image each time a new tab is opened. It was implemented as an extension because static Firefox themes do not support user interactions or event-based actions.
