It won't work & I can't access any support to tell me why. I've tried removing/re-loding without any su cess. What do I do to make it work?

Other formats but mp3 was NOT available. Dont bother with this one

muito bom

Converts to m4a not mp3, BUT it needs only read page permission on youtube.com, meaning that it's one of the extensions that I can trust.

Non funziona. It does not work!

It does not download YouTube videos as mp3. It downloads other file type and then you have to convert it yourself.

download in m4a and sends you to another link to convert to mp4. over 4h estimated time to download an audiobook.

Took a minute to convert one track and then refused to convert another one,

Link is now broken. Error code expired certificate
