Features & Capabilities

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.

User Reviews

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Some expectations are outdated (Twitter notifications not reliably supported)

Is Notification Sound Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Notification Sound requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Notification Sound has earned a fairly good reputation and likely can be trusted.
