15.6 works for me!

This isn't a scam guys, i've been in touch with the developer in which i got a quick response. When YouTube makes a change, this plugin then needs to be updated and it's a lot of work to keep on top of all. Consider making a donation to get it going long into the future.

Getting a zero (0) size file download. Broken for quite a while now, with others having same issue. Have emailed support and checked website, but no mention of a fix in-progress. Shame, because when it works, it's does what it says. Often breaking, though - which may or may not be creator's fault.

MP4 360p und MP4 720p:
Button text "pls. wait, this can take time..."
Download attempts lead to a file with size 0.

MP4 1080p (Full-HD):
Works, but sometimes with and sometimes without youtube file names.

On the so called support page it says:
"UPDATE 01-JULY-2019 : A fix v 15.3 for downloads stuck at "Pls. Wait" message is now fixed and pending mozilla's review and approval, this is expected to take upto 48 hours. You can check for latest v 15.3 here - https://addons.mozilla.org/en-US/addon/easy-youtube-video-download/ ".
The update is still not available today (11-July-2019).

This doesn't work anymore. Support page says download version 15.5 , but this version is not available here. The latest version is 14.4, from 3 months ago, while the support page states a new version was released on July 1st.

-- Edit: It works again!

-- Edit: Works!

easy to use... thanks

Correction of former statement: Since the last update it often is useful for downloading in 720p, if an higher resolution is available, that then can only be downloaded by plus-version. For many videos this is enough for me, especially, as there seem to be missing an alternative, since youtube changed its architecture. Sometimes only lower qualities can be downloaded.

good

best so far

Finally, a YouTube download plug in that claims to allow 1080p downloads, AND delivers what's promised. Even better, if you have any problems, the developer responds to emails very quickly (responded to mine in less than 3 hours), and works with you to resolve the problem as quickly as possible.
