Used to work well but not anymore. A huge thanks to Dars below for submitting a workaround with good instructions that works well with tampermonkey!

This extension doesn't work anymore ... BUT for a working alternative: 1 Download the extension 'Tampermonkey' which allows you to run scripts. 2 Google 'LibreScore' and visit the Github website. 3 Press on the pinned 'dl-librescore' link. 4 Install the latest dl-librescore file. 5 PROFIT. You can now download PDFs, MP3, and MIDIs from Musescore.

Borked :-(

Cannot download as PDF, errors get redirected to joining their discord server

Doesn't work, even with authorization.

Thank you for doing such a great work!
Music should be available to everyone :D
