the smoothest experience of ~20 tested similar add-ons
+ bold and clear 2-clicks interface, doesn't steal precious space on the toolbar (adding button on the page instead)
+ offers only few most appropriate formats
+ saves proper names
free version is limited to 720p mp4 (fair enough), reasonable donation unlocks hi-res and mp3 features.
worth to tell these limits clearly in the description though - to filter out hunters-for-free-beer.
recommended without doubts.

Excellent! It's very useful, all days I download videos for illustrate my work. Thank you, an excellent work with this addon.

Great tool, just the color of button... please, change it

Working great! Fast and easy!

FINALLY a simple to use no bog-down video D/L FF add-on, thank you! Worked for me using FF 56.0 32-bit on W7.

Best downloader for video and MP3 in high definition.
Immediate assistance in case of failure problems due to changes of youtube configuration from time to time.
Once I sent the request for assistance I immediately got the answer and I solved the problem immediately.

Thanks

Very intuitive aplication

Good

Although it sometimes gets difficult to download in lower resolution generally the videos are easy to download and very fast. I use Internet download manager and sometimes it can't take the download over from the extension (IDM accelerates the download significantly). Overall is one of the best and easiest video downloaders to use. Keep the good work!

Simple to use and less intrusive than the alternatives

great

Very easy to use.
