Introduction

This is a port of the UI Sounds extension to Mozilla Firefox. This extension plays sounds for important events in the browser, such as loading a page or opening a new tab.

If you’d like the browser to audibly notify you when things happen, then this extension is for you. Includes options to enable or disable individual sounds and change individual sound volume.

Background

At the start of 2024 I ran into some discussion on Mastodon about a Chrome add-on that plays sounds on specific tab actions and how its absence makes it difficult for some people to switch to Firefox. The add-on’s code was publicly available, but did not have an open source license attached, so I requested copyright clarification from the maintainer, LordLuceus. They licensed the code under MIT soon after, but I only found out by happenstance in September of 2024. I put together a port of the extension’s code to Firefox, submitted it to AMO, and here we are. Hopefully it will be useful to some.
