This extension has gotten so good, and especially with the companion app, so I have to leave a review. It can download damn near anything.

Even in the rare cases when you can't download a stream btw, you can copy the video link using the extension, which will likely download a m3u8 file. Then you can use VLC to convert it into an an actual video (note the links in the m3u8 file should be the full ones, not relative ones, so fix it if needed)
