3 years ago, this extension used to be the best extension to download youtube videos!
Thank you for you work and may you rest now, old soldier. ^^

Worked for years as an excellent addon and I had given it 5 stars previously, but since October 2021 has become very slow, taking ages to download e.g. a 400MB video 2 hours long take 2 hours 38 mins to download, so longer than the length of the video!

To anyone who's having the "Batch downloading interrupted" error while merging video-only and audio-only files I have found a fix for it.

What you wanna do is:

1. Change "Save merged files in" location to your desktop, e.g. "C:\Users\USERNAME\Desktop"

2. Make sure these boxes are checked:
[ x ] Combine video-only and audio-only files (if FFmpeg is installed)
[ x ] Always download HD quality audio for video-only files
[ x ] Remove download file(s) after successful conversion
[ x ] Always ask for download location
[ x ] Post processing (if FFmpeg is installed): [Extract audio]

And then hit the "Save" button.

Also make sure your FFmpeg Integration is working.

When you start downloading video and audio files you'll be asked where you wanna save those files, save them in your desktop and once downloading is finished the merging process should be done.

NOTE: If you're choosing to download the MP4 versions of the video-only and audio-only then you need to choose a different download location for each one of them (audio-only and then video-only), otherwise you'll get a different error (because both audio-only and video-only versions have the same name, and renaming them will screw up the merging process.)

The WEBM counterpart does NOT have this problem.

The extension has stopped downloading separate audio and video files (such as 1080p); when the audio file completes it says 'failed' for that file, which then cancels the video file downloading. As a workaround, download the combined 720p file first and then try downloading the 1080p video and audio files and it will *usually* complete the download and combine the files as normal.

It used to worked fine. But recently downloading audio only doesn't work anymore.

Previously was a great Firefox extension.

There is an error when combining audio and video files: "cannot find the file". Problem started a few days ago.

Also, another popup appears during downloads: "Batch downloading interrupted" when audio stream download is at completion but video stream is still downloading.

Not usable anymore.

Excellent app. It was working fine till two days back. After the last update the mp3 converter window does not open at all. and keeps showing busy status for hours together.

Works easily -- checked with Youtube -- to extract an mp4. Just what I needed.

It used to work fine, but now it isn't. It always fails midway through the download.

This app used to work great and reliable and a 5 star app. After updating to version 1.0.2 and Firefox 76.0.1 (64-bit), it fails to combine video-only and audio-only, with a popup saying "Batch downloading interrupted" when audio stream download is at completion but video stream is still downloading. If this can be fixed will once again be 5 star rating. Thanks

Yes, this is a duplicate review, saved me the typing. I'm having the exact same problem now.

Used to work all the time, but now whenever I try to use it I get an error saying "Cannot detect url_encoded_fmt_stream_map, adaptive_fmts or adaptiveFormats"
