- A whitelist (never muted, even with auto mute enabled).
- A blacklist (always muted, even with auto mute disabled).
- A context menu to add domain or URL to whitelist or blacklist.
- Ability to mute all tabs and unmute all tabs from the context menu.

If you don't need the additional features, you can use the original extension https://cup.aihedy.com/en-US/firefox/addon/auto-mute
