## Description

**Notification Sound** is a Firefox extension that brings audio alerts to your notification system, complementing the default visual-only notifications. Customize which websites and supported extensions trigger sound notifications, either by including or excluding specific sources. You can play sounds for download completions and notifications even when Firefox isn't focused.

The extension allows users to define custom sounds or use the default pop sound. For greater personalization, individual sounds and volumes can be assigned per website or extension. Note that it does not work with push notifications sent when websites aren't loaded in a tab, due to technical limitations.

Notification Sound supports integration with specific extensions such as Advanced GitHub Notifications, Netatmo CO₂ Indicator, and Update Scanner, and respects notification flags like silent and sound options. It requires permissions for storage, download history access, browser tabs, menus, and website data to function seamlessly. Developers can also integrate this extension easily using the provided documentation link.

## Review summary

Reviewers praise the add-on for simplicity, usefulness, and per-site sound control, especially for Teams/OpenPhone. However, reliability is inconsistent: many sites don’t play sounds, and Firefox compatibility and permission-related errors are common. There are also initialization/testing issues and some feature requests (like hiding the tab context menu). Overall, helpful for specific apps and before system notifications, but cross-site sound support is not dependable.

### Pros

- Simple, easy to use and convenient
- Customizable notification sounds
- Per-site muting/control of notification sounds
- Helpful for specific apps like Microsoft Teams and OpenPhone
- Fills a gap before Firefox/system notifications were widely supported

### Cons

- Inconsistent across sites; many popular sites (Facebook, Twitter, YouTube, Instagram, Twitch, Telegram, MoneyControl) fail to trigger sounds
- Compatibility issues with newer Firefox versions or after updates (some users report it not working or instant failures)
- Permissions and privacy concerns (requests broad permissions such as read/modify download history; some sound play attempts are blocked)
- Testing/initialization bugs (sound test and preferences can produce errors or silent results)
- Some expectations are outdated (Twitter notifications not reliably supported)
