Custom Sounds od Kirutre

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.

⏭️ New Features!!!
+ Volume Control: because only you should decide how fast you want to destroy your ears.
+ Multiple keys, same sound: so you can assign your favorite sounds to your keyboard.
