While it's working, it works great. However, Youtube broke something again in the past week or so and this stopped working... either I get "Batch download interrupted" or it won't find any source even when the video is playing. However, selecting "Quick download" seems to work for either error on some videos, although it seems to default to highest quality video and audio with no way to choose a preferred max size/format. While this is normally good, for 4k videos this can be a pain - I don't need anything bigger than 1080p, so it's just taking up more storage than it needs to.

not working any more. hope you gonna fix it.

Not working anymore..... Useless app!

Has again the problem " Batch Download interrupted" tried on several different PC's.
Its not working.

No download link, argh!

Cuando un addon es sencillamente insuperable por el increíble buen servicio que brinda a sus usuarios, sencillamente, se crea una conciencia global, poderosa e invencible que devolverá al Rey lo que es del Rey. 5 no... ¡10 estrellas! Es cuestión de tiempo... y nosotros estamos aquí para darte todo el respaldo que mereces. Very great Job indeed, Feller!

One of the best add-ons I've ever used. Sadly, Google has made changes, and it's not working. Let's hope the developer can fix it.

Know it is (quite likely) not the author's fault of not working... and will be waiting for it come back again.

This is the best Firefox addon, I hope it will be working again soon.

Made an account to write this.Until it recently stopped working this was the very best, thank you. Here's hoping you legends get it back there.

What is the best alternative?
