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.

6 months ago:
[published_date] is always as "undefined" in file name.

Today: [published_date] still not working.
Also cant use '[' , '(' and other special symbols in the file name.

The downloader is fine. I want to know why the god damned preferences page opens every time I download something!

No sound after downloading 420p video.

Quick download option downloads only a low-res video even if you are watching the HD version playing in your browser. Does not display high bitrate download options for videos. Audio is downloaded separate from videos.

I'm trying to install native client (from link on github.com ) in kali linux 2020.1 , firefox 73.0.1 - after command ./install.sh(everything fine) still doesn't see as installed in YouTube Video and Audio Downloader settings tab.... I'm upset
