This is a firefox fork of a chrome project that can be found here:
https://github.com/vazbloke/spotify-desktop-ify

Open Spotify URIs/web player links in the desktop app every time

This redirects Spotify content links to the Desktop app. Click on any song/playlist link to test

- Doesn't navigate away from the current page
- Auto-closes if opened in a new tab
- Doesn’t autoplay and interrupt your music
- Supports all content types (songs, playlists, concerts, podcasts, users…)
- Can still use open.spotify.com - only redirects direct content link-clicks
- Strips tracking ID in the link - for better privacy
