Great.

超好用

非常棒，非常感谢

Excelente programa, muy útil. Una de mis extensiones de Firefox imprescindibles y más recurrentes

Best web crawler and video downloader ever!!! It even allows the user to choose between different video qualities... 10/10
It crashes sometimes, but that might be due to some servers' unstable situation.

Top Tool. Funktioniert immer, selbst wenn bei anderen guten DL Helpern nur noch Minidateien erscheinen.

Excellent for video download, better than any other addons.

Must have!!! You can't live without this software. The first addon to install

It's pretty good. I can download videos from popular sites to watch later in places where an internet connection is unreliable/unavailable.

I like the add on and it's simple to use.
Idiot proof, I'd say.
When video is ready to be downloaded it simply starts to glow the icon. And once you click icon it'll pop up a list of formats to choose from.
Only minor thing I'm missing is ability to define my favorite resolution, so for example I'd like to get 720p link as first possible option and 1080 as second. Or have fixed order always, but add-on is trying to remember my previous choices, but sometimes it mix the order of the formats/resolutions so if you are downloading few videos in a row then first choice in the list is not always what you prefer, so caution and reading the offers in details is needed.
Also page title is displayed in download options pop up, which is helpful, but it seems to be in fixed and quite big font and if page has longer title, then it's not going to fit.
In general I like the add on, using it time to time, and I thank those who made it, because it's true helper.

easy to use and stable.

Very very helpful add-on, highly satisfied with its performance.
