Succeeds where others fail. Works well except for the highest HD videos. Those are streamed by YT as separate audio/video. This fails to capture and then merge those separate HD streams. However, 720P is good enough for my research purposes. Not looking for a theater experience. Addon may present too many confusing options for noobs, tho.

Since around 1 year, the extension doesn't merge the audio file with the video file anymore : finally, we end up with a video without sound.

the only application that allows me to download private videos from you tube

it works

It is a MUST add-on for FF w/YouTube

It used to work but at this point? Not sure anymore.
Downloads both the audio and video but doesn't compile em. And if it was doing it there is like Zero notification on the progress.

I had used it for so long, did a really great job. Now it stopped working because of "Batch downloading is interrupted", its a pity.

Installed the executable and ffmpeg and included the path. And then NOTHING.No logo below videos. NOTHING.

it's work! Thanks

works fine but the download speed is very slow

Há muito tempo eu a uso, mas de uns tempos para cá ela não transforma em mp3 somente mp4. Gostaria de saber como consertar isso.

Downloads in VP9 where possible in all qualities. Unfortunately you sometimes have to assemble the separated video and audio file with ffmpeg through terminal.

It's really slow

nice but... not working, worthless
