great

Great program and easy to use. So far the only sight I haven't been able to download is xhamster.

Ugly and sometimes difficult UI. And it will place an ugly watermark on some of your videos? Which ones? When? You'll find out AFTER you've waited for the video to be created. I'm fine with trying to make money, but this is a shady plugin that you should not trust.

相当好的软件，赞！！！

很方便好用的附加套件

I particularly like the simplicity of it. Spot on Software!
I warmly recommend

Great so far.

Excellent add-on, can download from streams where I thought it wouldn't be possible!

very good

Complex, baffling, large watermark unless you send them money ...

Requires an additional payment on top of what was previously paid. I will never use anything from this plugin author ever again since he has a history of literally trying to make a living from his plugin.

Very good video download add-on tool! 非常有效率的影片下載外掛程式，極力推薦!

Fantastic little tool that is incredibly handy.

不錯用

Downloads Youtube videos as webm which is fine. Not so fine is the QR code watermark stamped in that needs a paid licence to remove. That info should be upfront, before download and install, not afterwards. A pity because I like their ethos, their transparency around donation problems they found using Paypal (tl;dr use stripe.com, not Paypal) and their support for Kiva donations. As they say, they need to eat too. Just let us know about QR codes first :)

Very good add-on, works very well.

非常好用的元件..大部分網頁視頻都可下載..不給5星的話太沒良心了^^

The best add-on I had used on firefox year by year.

Super
