I have serious suspicion that this addon causes memory leak and CPU overload at youtube live streams. One of the firefox.exe processes took full CPU core and a couple of GBs of RAM. When I turned off VDH addon, the values went back to normal. This issue can be mistakenly credited to firefox itself, so please, if you have similar symptomps, try to turn off all addons.

A bit wonky at times (you have to keep the site open with the video to download), but still one of the best, most easy to use, and most reliable download services out there.

Ez az, ami nekem kell!!! Szuper jó és egyszerű használni! Mindenkinek ajánlom, nem bánod meg!

Taugt gut f Download v. Apps. Konvertieren v. Videoformaten nicht logisch erklärt und langdauernd...

Works great, there is a separate download needed but after that,you can download things from places you normally couldn't, such as Twitter Dms

Promts me to install another program in order to proceed downloading a video. I reported this to mozilla.

Macht was es soll. Nicht jedes Video funktioniert. Aber viele Videos gehen ohne große Probleme

It works, slowly on some sites. It is pretty good for free software. Gotta thank the developers for it--thanks!

Ein tolles Addon,funktioniert großartig.Vielen Dank an die Entwickler!!! :)

Je suis très satisfait de cette extension, merci.

非常好用的插件，下周腾讯课堂的利器，大大的好评

Absolutely fantastic. So easy to use. Wonderful. Thanks

Works on most sites (streaming, Tubes, social media). Super easy to use.

Замечательное дополнение. Работает отлично. За все время пользования не было сбоев в работе. Я очень доволен и убежден, что все кто установит его будут такого же мнения.
