Downloads audio-only when I select movie+audio

So many of the Youtube downloader extensions redirect you to shady third-party sites with loads of ads to do the downloading. This does direct downloads from Youtube, and while it appears to integrate with FFMPEG, it doesn't require it. This is the one to get.

Only one minor niggle; would prefer to have the list of formats available in the download panel available from the popup; I use a greasemonkey script to make the video player full-screen and it doesn't play nice with the extension, so for anything but the quick download I have to disable that greasemonkey script. But it's a minor thing, I can disable the greasemonkey script when I need to.

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.
