Download Audiobooks .mp3 from Libby (not OverDrive!)

Hi all,

I've recently come across this great Firefox plugin to download .mp3 files from Libby (not overdrive). This makes managing your books way simpler as you can use your favourite audio player.

When I looked for similar services I could only find difficult solutions on Reddit. Posting this on Lemmy only.

**NB: keep in mind you should delete the audiobooks once you get past your expiration date. **
