Site Sound is a Firefox extension that lets you manually enable and control the audio volume for specific websites. It is intended for sites that do not already have their own volume control.
- Manual Per-Site Control: The extension is off by default. You can enable it for any website using a simple toggle switch in the popup.
- Remembers Your Settings: Once enabled for a site, it saves both the enabled state and your chosen volume level for all future visits.
- Simple Volume Slider: When enabled, it provides a slider to control the volume (0–100%) for all audio and video elements on the current site.
- Dynamic Content Support: Automatically applies your volume setting to new audio or video elements, including those loaded as you scroll (like on Instagram).
- Safe and Private: Does not boost audio above 100%. All settings are stored locally in your browser.
- Click the Site Sound icon in your toolbar.
- Use the toggle switch at the top to enable Site Sound for the current website.
- Once enabled, use the slider to set your desired volume.
- Your settings for this site will be saved for future visits.
- Best on sites without their own volume slider.
- No boosting, only 0–100% volume.
- Minimal permissions required.
