Just show the message "No videos found" for the all sites and videos that I tryed.

siip

embeded vimeo video on site showed 50 segments whih all were about 100 kb. did not work at all

Dec. 28, 2019 - I have to agree with many other users - this extension does not "see" videos and cannot download anything. I went with the addon from VideoDroid. That one works, and works well everywhere I have tried it.

I also see that this has not been updated since May 31, 2018. That is probably why it does not work. The developer has not kept up with the frequent video website changes.

Uninstalling.

I have never ever managed to download anything with this app. All I ever get is
"No videos found
Please try to start a playback
if you see a video on the page"
even well into playback!

Incroyable, j'installe , je recharge la page et HOP il trouve la vidéo.........Magique...Logiciel EXTRA...Faites comme moi ESSAYEZ-le c'est l'adopter

aplikasi kontol , tidak bisa unduh yuo tube.

Can't see the logo on my imac /Firefox screen toolbar

It does not work on the only website that I am interested into: archive.org.
Anyway I would never install it in my main browser, because it can see all my passwords and other things that I write.
