ok

Works well to download 640x360 videos, but latest Youtube code changes means that it no longer can download HD and FHD versions of the video.

How to remove the number in front of the downloaded file

Works, but if your browser window is too narrow it will push off YouTube's "more" (...) button so you can't add the video to playlist, etc. unless you increase the window size or disable the addon.

Only allows mp4 format.

27-06-2021 funcionou. it worked at this time. let see for more years.

Rough around the edges, looking at the colors in the dropdown box, and a bit too minimalist UI, but the current version works nicely. (1.6.27)

Has worked reliably for years until two weeks ago when I downloaded a now-banned video. I can no longer see the download button. Since then, I have tried to use other YouTube download add-ons, but they do not work either, so maybe the problem is on the Mozilla side or YouTube side. I see that there are "Mozilla recommended" add-ons, but they require invasive levels of permissions.

UPDATE: I uninstalled and reinstalled. Now working. (Disable-/re-enable did NOT work).

it is very good

2 choices are available "normal" AND "HD 720P", I don't know why the first video I tested there isn't HD 720p available. But it seems that most of the time 720p is working fine,
thanks for your work !!!

This add-on has worked great off and on. Currently it is not working. Needs an update. Great app when working! Thanx Igor

GOOD
