This addon suddenly stopped working on 11/23/2023, and after uninstalled then reinstalled and it back to work again, turns out the Companion Application is outdated.
However, now I cannot change the download file name anymore. Bad update!!!

This is a great add-on for creating archival videos! Well worth the small donation they ask.

使用方便，好用

By far the most effective tool I've found for downloading videos online. It doesn't always work flawlessly but it outperforms everything else I've tried by a wide margin.

VERY GOOD ONE I FOUND NO ALTERNATIVE
