Reliable, intuitive, up-to-date, hassle-free, great.

Absolutely great add-on, thank you to the creators for it.

When I downloaded it the first time it worked well (a long time ago, talking about years ago).
Now the download speed is "meh".
If you download multiple videos (across many tabs), it will crash and it won't say which videos weren't downloaded (it only appears to report the bug).

It would be more helpfull if it wrote also the video titles where it failed so thwey can be downloaded again.

Ad-Ware. Should be removed from recommended Add-Ons!
Bakes QR code into downloaded videos to pay. Tells you about this only after you installed everything and downloaded your first video. VERY scammy tactic! :(
Use yt-dlg instead.

使い勝手がいいです。
素晴らしいアドオンです！

Used to work well, now it inserts a giant QR code into everything you download trying to extort you to pay for a "conversion license" without giving you the option to just download the source format without converting.

とても使いやすく問題もなく使用できています

First of All – “ A Big Thank You “ to Michel Gutierrez - the French software developer – The Single Handed, Originator & Founding Father of Video DownloadHelper, in the Year 2006 –
and also thanks to the team now in 2025 (maybe -not sure) , that keeps it running Smoothly.
I also Thank Michel, for the generosity and kind courtesies, for keeping this gem a software “Free” for people to use. I came across this software only around 2009-2010 and since then have never had to look back for another software for video downloading from the internet , and Never Would –
Whatever and Whenever I needed to download a vid – a Blind Click on the VDH logo and DONE !!! the downloads would roll in. I use it across all the 3 platforms Firefox, Chrome and Egde, Why ? Because of Its browser "Compatibility", thats the next Best Thing about Video DownloadHelper – And this Software is CLEAN – no adwares, spywares, tracking, no viruses.
Video DownloadHelper, is The One and Only of its Kind, that is, and that will ever be.

Stopped working, QR code is unnecessarily large.
