About this extension
It allows you to add audio files to be played while browsing; these can be MP3 or WAV files. Other extensions have not been tested. You can assign a sound to browser events (such as opening or closing tabs) or keystrokes. The extension requires injecting JS to capture when a key is pressed, therefore permission is requested for all websites.
The extension is open source and available on my GitHub. It's my first project, so I hope you like it xD
