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.

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.

Only support 1080 video, no audio

Heartbroken. The old version worked perfectly. The new version won't save to my desired YouTube Download folder path, and will not extract mp3 audio despite manually typing in the path to FFMpeg. Any chance on updating the old version that worked?

I will repeat what many others have repeated. I couldn't say it better than Anonymous user c94bff said 15 hours ago:

The old version let me do what I want to do, which is download the video and the extracted audio. It also REMEMBERS where I last saved a video/audio combination, so I don't have to keep traipsing around my hard drive to find the place to download.

WHY would you take a perfectly good program and break it so that it is only useful to complete tech-heads? It was fine before. It did what needed to be done. I have fiddled with this new version for about an hour now. I am done. GDit. I am so tired of having to go find alternate versions of things after the good version is broken by "improvements." What is wrong with "you people"?

The instructions say:
1. After installation, go to the options page and
-> 1. Install the native client (This is a small NodeJS client written by @andy_portmen)
-> 2. Install the FFmpeg executable
2. FFmpeg integration is required if high resolution video or audio files are preferred.
My questions are:
Where do I find the options page?
What is FFmpeg integration and how is it done?

This new version is a disaster to install and get it to run and it doesn't remember its last download location. I've chosen the option to not download audio, and the first thing it does is prompt me with a location to download an aac file. It's lacking a lot of customizable options Please do something about this, the previous version worked like a charm. This works like a nightmare.

Not clear on how to make it work. Options menu never shows.
