It works, but there's room for improvement. The red badges remain even after downloading.

To download, you need to right-click and select 'Download with yt-dlp' from the menu, as clicking the icon results in a "file not found" error.

To adjust parameters, you have to modify line 44 of the installed "yt_dlp_firefox" Python file. The save directory can be changed by editing line 34.

My settings:

Line 34:
DOWNLOADS = Path("M:\\New Shows")

Line 44:

["yt-dlp.exe", "--print-json", "--recode-video", "mp4", "--postprocessor-args", "FFmpegVideoRecode:-c:v h264", "--", url], # Use yt-dlp.exe on Windows
