  "description": "This extension makes Deezer share normal links instead of link.deezer.com URLs.\n\nNormally when you use the share button in Deezer, it generates a link.deezer.com \"dynamic link\". This link, when opened, redirects to a long URL that includes several URL parameters. One of these is your account's user ID. This means you could potentially dox yourself by sharing a song. Additionally, the dynamic links are actually longer than normal links, and add a redirect when loading. This extension intercepts the API request for getting a dynamic link and just returns the normal link.",
