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.

目前唯一有效下載YouTube原始串流影片的附加元件，且能抓到所有畫質供選擇，而非常見的下載轉檔垃圾。

I am using Firefox Quantum 59.0.2 with windows 8.1. After installing the other supporting apps, I have used this program many times with out fail. Great app works like it is supposed to.

es una ayuda extraordinaria, Nikolas

I was using this extension from more than 7 years. It's really fantastic.

Works partially : only the video-only and audio-only files are correctly downloaded ; there is an issue with "normal" files : only the audio track is downloaded.

Funktioniert tadellos, besser als alles andere, zuverlässig und schnell,... topeinfach, einfach top! ...

Muy buena...

It is broken. Youtube has changed something to the effect that the video file extensions and the audio file extensions are switched.
The workaround (manually renaming the files as they are saved to disk) is kind of a pain in the ass.

Also, switching the "Homepage" from:
https://github.com/inbasic/iaextractor/
to:
https://addons.mozilla.org/en-US/firefox/addon/youtube_downloader_webx/
would be very nice.

Very good addon/works well. I would like to see it have an option to remember the last folder saved to, as I save to many different folders and it gets tedious to have to drill down to a specific folder when downloading similar videos each time.

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

Good

Works really well with Youtube. :)

virus un .bat comme d'hab ( j'ai même pas télécharger l'extension ptdr(plié tordu de rire) tas de merde !

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...

It properly enlists what is on the Youtube website. The best part is to download the Audio-only file which was one of the features of Flashgot, but not working in Quantum.
Thank you

That is the best
