Works well enough and integrates pretty nicely into youtube.

Sometimes the extension will stop working because youtube changed a few things. When that happens, updates usually seem to arrive within a few days.

I've seen some people complain about this extension not offering video+audio streams in certain resolutions on certain videos, but that's hardly developer's fault (since they just "expose" the download links that youtube player uses. If a stream of certain resolution and/or audio quality is missing, it's because Youtube no longer supports that format of stream).

This was a 5 star add-on until this latest update. Now I get this error:
signaturelocal: cannot resolve signature;3

К сожалению, не скачивает видео в 480p и 720p (скачать можно без звука, хотя раньше была возможность скачать со звуком). Если бы скачивало - была бы, похоже, единственной работающей качалкой со всяких ютубов.

Don't wast your time with this add-on, go for "Easy Youtube Video Downloader Express" instead because it works !

good

The downloads are now taking forever. Usually a few minutes and now up to an hour. Is this happening to anyone else?

Way too slow.

Cannot detect URL of new videos any more.
Fails to combine video and audio files. Does save video and audio files separately. Asks to install a native client and FFMPEG applications, but even after those are both succesfully installed and the browser is supported, fails to combine the video and audio files.
The video tutorial for installation is horribly poorly done, and doesn't even show the extension's option page.

I can not get this once great extension to work at all.
