Extension Metadata
About this extension
- Auto mute — Mark a site once and it's muted whenever you visit it. Settings live in
storage.sync, so toggling it on any device applies everywhere. - Volume control — Two independent levels:
- Page volume: applies to a specific page URL (query/hash ignored)
- Site volume: applies to the whole site
- Multiplicative: effective volume = page volume × multiplier, adjustable 0–500% without steps
- Priority: auto mute > page volume > site volume (volume settings are ignored while muted)
- English & 中文, light & dark theme (follows system)
- Manage all settings in one place: site list, batch delete, export/import (merge or overwrite)
