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!

20Euro price for this Addon - NOPE

Заставляет установить стороннюю программу, тем самым внося свой вклад в захламлении системы, вместо стандартного меню загрузки используется какое невнятное меню, в котором легко запутаться и можно скачать что-то "не то". Раньше скачиваемое видео было нормальным, теперь всё оно низкого качества. После сканирования антивирусным сканером, утилита удалила файлы этого плагина, посчитав вредоносными, а после повторной установки расширения перестал работать спящий режим. Есть подозрение, что в расширение вшили майнер.

с не зашифрованным медиа контентом делает свое дело на пять баллов!

Easy to use.
