It fails sometimes, but is a great AddOn, only needs a little more polishing :D

Honestly this is the worst way to download any video since it plasters a terrible QR code on your download telling you to upgrade/pay. There are quality and actual free solutions to download videos on these websites. While this extension has 4.3 as an overall rating now, there is no way that will remain the case for long with how this extension is operating.

perfetto download

very helpful. I downloaded tens of videos in a few clicks

Such a garbage add-on.

Perfection.

can't use the companion app

I am using the Video DownloadHelper since years now: Best piece of software to download videos with Firefox ever!

The best extension, hands down, for downloading videos without built-in download options

Happy with this software, it works wonders!

使用體驗良好

Has given me a lot of help

Best video downloader I've ever used, works everywhere. May find more than 1 resolution video on page or more than one video, use the video play time to make sure you get the right one.
Update: taking one star away because now, in latest upgrade, seems when a download fails, it gives an error to send a report, BUT DOESN'T TELL THE USER WHICH DOWNLOAD FAILED! It used ti do that when it was just a dropdown from the bar.
