Doesn't work.

shakil

useless

Cant Find the Button in youtube.Using Latest Firefox. Fix this and i will give 5*.

Youtube video and audio downloader doesn't install native client properly, and doesn't combine audio and video in downloaded mp4 files. Do you know how to fix that? Thanks.

Does not work on Firefox + Win10. Crash during combining audio and video after download.

Does NOT download both the audio and the video and combine them for you. 3-19-18 Firefox 59.0.1

pas de conversion mp3, le fichier en supplément dans le module firefox demande de télécharger un logiciel a pars de firefox (2 modules et un executable en plus, de la merde...

No support for 1080p.

keeps saying youtube signatureLocal: Cannot resolve signature;2

unable to download anymore

No longer works as of 14.02.18 gives this error, "youtube signatureLocal: Cannot resolve signature;2", I changed nothing I downloaded videos last night, I try today it gives this error I was even using the old version new version none works no more.

Quick Download button does not work like it used to be after Firefox Quantum update. It doesn't download 1080p anymore. It doesn't download m4a audio files either. Very frustrating to see such nice apps go bad. I had to switch to a stand-alone downloader software.

Addon is broken.

Very slow download speed opus format!!!!! (50Kbs)

I download the audio portion of videos. With the old app this was simple, as it downloaded the mp3 along with the mp4 with just a couple of clicks. Now I get just a video file and the process it extract the audio is beyond me.

Hopefully this app can be improved to make it as simple as the old one.

Sadly, no longer works for me either

Imposible download the FFmpeg 3 steps

Old version was better and worked out of the box. This version wants you to fiddle around and even if you follow instructions to the letter STILL gives an error message.

This can not do anything the one for the old FF did. A big disappointment. Just isn't usable here. Have to find a new add on, sad day. Really liked the old version. If you fix this post it somewhere, hopefully i see it and can come back.

The Web Extensions version is bad. Previous one was much better!

I do not see a place where i can down load the video and have the audio down load as well, I i can not find it on the options page at all there is nothing to down load or add to so that is automatic.Maybe one of you guys can do it but i can not at all.The old Youtube Dowloader had a very simple way to get it all.

I followed all instructions you claim work and I still get the error message about "something that went wrong" and if i have the client installed... I didn't miss anything during installation and I keep getting the same crappy error!!! Please provide a WORKING SOLUTION or a workaround for this or a decent alternative. Thank you.
