Librezam wot FoxRefire

This extension is a browser extension that recognizes music currently playing in the current tab using Shazam's internal API and multiple alternative backends.
No telemetry or other communications unrelated to music recognition are performed.
To learn about the characteristics of each backend and how user data is processed, please see the Privacy Policy section.
This is an unofficial project and has not received any assistance from Apple Inc. or the providers of alternative backends.

===Troubleshooting===

• Media elements not detected on some sites, site-specific issues occur
  Some sites may not start recording correctly due to DRM restrictions or site-specific issues.
  DRM restrictions cannot be fixed, but if site-specific issues occur, please report the problem and details via GitHub Issues.
  Pull requests to fix issues are also welcome.
  Please do not report bugs in the review section.

• Media elements not detected on all sites
  This may be because the extension's site permissions have been revoked.
  This rarely happens when updating add-ons.
  Open the add-on settings permissions tab and allow the "Access to saved data for all websites" permission.
• Songs are not recognized
  This extension's music recognition processing depends on each backend, and only the Shazam backend is used by default.
  If songs are not recognized correctly, try adding different recognition backends or adjusting recording time from the extension settings.
  Also, while Google's music recognition feature is not yet integrated as a backend in Librezam, it has very high accuracy, so it's worth trying
