Update 25.06.2021, add-on version 1.1.5, Firefox 64-bit ver.89.0.2. Download Panel stopped working long time ago (Error Message: info.player_response is undefined.), so I was lately using Quick Download. This one stopped working, too. Simply says "Please wait" and no download is initiated at all.

After updating to the latest version, the plugin stopped working. He gets the message "Batch downloading interrupted". I installed the old version 0.9.0. It's kind of buggy but the videos are downloaded correctly. Youtube seems to be starting to block the possibility of downloading clips.

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!

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.

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.

App shows "Filename must not contain illegal characters" constantly, when all characters are very common A-Z letters, & I never even changed anything to begin with. This is an awful app: it has a simple purpose, & just won't fullfil it at all.

Error messages, when the only thing I click is to download, is unacceptable.

There is an error when combining audio and video files: "cannot find the file". Ffmpeg and software are installed correctly.

May 11 2020, it's working again!
Jan 12 2022, stopped working. Went back to earlier version, but now it doesn't combine files.
Dec 2022, not combining files. Looking for something else. March 23, no longer combines audio and video.

Two other add-ons and an application to install just to download a video or convert one? Streamline it or warn people. Do better. Uninstalled.
