31-03-2024: doesn't work anymore since around last 3-4 weeks, can only download 360p video (no 720/1080p anymore) and when you choose to download 360p it downloads a video with black screen and text telling "this content is not available in app, please watch it in youtube".
edit 05-04-24: works again great, thank you for applying update. i was using it 2 years successfully and just last 3 weeks stopped working completely at all, thus i wrote this review to let u know it was not working.
I have fixed this and you will receive an update via auto addon update in firefox once it is reviewed there. If you are on Google Chrome or Microsoft Edge you need to manually update by visiting this download page.
It's disheartening that many satisfied users don't leave reviews while a few unsatisfied ones do, that too after using it for years but not working for few days :(
