I have another perfectly working video downloader, but since it is 'legacy', decided to try this one - it can't see any media file at all.
Just noticed - 'last update' a year ago, why this crap marked as "Featured"? Mozilla, anybody home?!

I Just wanted to try a new browser experience,looks hopeful!!

Nicht notwendig,ihr seid einfach super

No Youtube, no option to select the download folder! I think in November I must SAY GODBYE to Mozzilla FF ! No video capture, no FF 57!!! Wellcome GHROME!!!!!!

You can download video or copy link.

An addon is NOT subject to their restrictions. The user is.

Can someone please explain to me why a web extension for Firefox is subject to Google Chrome Web Store policies, in relation to why it won't work on YouTube?

I was under the impression that that restriction was only for extensions and apps within the Chrome Web Store.

Good..

It has a lot potential, but needs improvements to work properly.
It doesn't detect every video and it detects files without size that aren't videos.
Downloading doesn't work not mentioning it just automatically save file to default location.
Copying opens a small window with the link that needs to be copied manually. Why it can't just copy link to clipboard without opening any windows?
It would be nice if it could instead of downloading with browser send the link directly to download manager.

Works fine for me, but I will look for another download helper. Since I'm not told where a file will be downloaded and have no choice, I have to move every file after downloading. Rather bothersome.

Complimenti questa tua applicazione è davvero fantastica, e facile da usare, anche per una persona come me non molto esperta.

Nice
