VERY GOOD!!!

很好用

The addon require companion software to be installed while other addons are perfectly capable of downloading directly. How can we make sure the companion software is not compromised.

Close to perfect. My only complaint is that sometimes it causes Firefox to freeze when closing a tab.

很好用，帮我解决了大问题了

At first I thought that having to install a separate application to accompany the extension was annoying, but for something that works well across many sites, doesn't appear to have ads, doesn't inject watermarks into the downloaded videos, and only occasionally asked for donations, I am quite happy with this.

très bon produit, très satisfait, je recommande.

Beware: Works only occasionally - but usually requires a "companion app" that Apple won't let it download because developer "has not had it checked for malicious software."

Video download helper has worked flawlessly. Absolutely recommend

Excelente me ha servido de mucho, ampliamente recomendado

super

Best one yet! Replaced all others I've used.

一个超好用的插件，好评

Eddig ez a leg sikeresebb videó letöltő kiegészítő amivel találkoztam! Aminél már másik kiegészítők bedobták a törölközőt ez ott is jól vizsgázott! Remek szoftver!

"Video Download Helper." It does what is says on the tin. It consistently outperforms anything else out there. I rarely use anything else.

Completely useless. Puts a pay-wall watermark on youtube videos. Use an open source free program instead.
