Firefox extension for Overdrive.
Only Firefox supported
It should work in every browser that supports Manifest v3, but will require manual instalation with all the associated problems.
Allows you to use Overdrive as if mp3/odm download was still available.
Just go to https://yourlibraryid.overdrive.com/account/loans and next to each audiobook you'll find a button that allows you to download the .odm file.
Use whatever tool you used to use to download the mp3 file from the odm.
I use my fork of overdrive.sh.
Shamelessly adapted from https://gist.github.com/ping/b58ae66359691db1d08f929a9e57a03d to use pure DOM functions.
Also removes some stupid libby elements.
