This extension flat out DOES NOT WORK. It asks you to install an external application, where the "install" button to install said application does absolutely nothing.

Annoying.

First of all installation: It requires a "helper program" to be downloaded and installed to your PC separately.

Then the plugin downloads the video, but spends your CPU cycles to add an annoying QR code for the developer to the downloaded video, adding BOTH delay AND annoyance to the download process.

If I wanted a QR code added to the video that I want to save, then I would ask for it.

Useless and annoying. Don't bother installing this

Very nice for casual use. Works as advertised.

This version 7.6.0 works far more smooth than any others.
Esta versión, trabaja mucho mejor que las anteriores.

Requires companion app for the last few years. Unnecessarily resource intensive.

The MOST universal video downloader add-on for Firefox there out there. Been using it for FREE for years, but just sprang for the $28 registration, so now it can even convert videos without the watermark. (Free version converts, but puts a QR code in the upper left corner.) I only wish I had given them my money sooner. Polished and feature-rich, you quickly get a feel for which (of the dozens) links to download. So, it's quick to learn, and POWERFUL for power users like me. 5 FULL stars! :)

I would like to thank developers for this app, pity but i cant donate from russian card because of sanctions(

Is this fake? Installed and does not appear at all even after rebooting.

A very good video downloader. I am using it for years. Downloads almost anything. Easy to use.

I am using video-downloadhelper for more than 12 years. From my personal experience I can confidently opine that it is the best.

adding a watermark does not seem like a good idea to me I have a slow pc and I have to wait for it to download and wait for them to put the QR as a watermark.

Memory Leak recently (20GB Ram usage even when closing everything), sporadic high CPU usage for no reason, sometimes 30% on an modern 8-core CPU, again even when closing all tabs besides an empty tab (the extension wasnt used or opened at all in either of those situations). Firefox performance analyzer clearly showed it was coming from this extension.
Besides that, the user interface is clunky and doesnt work correctly if the extension icon is moved into the dropdown menu.

Video DownloadHelper is a very useful add-ons, you can exactly use it to download videos easily.

Watermarks videos unless you pay.

This is a fantastic video downloader and I very highly recommend it!

excellent service merci

Easy to use, stable, good cone click selection of resolution/filesizes
