The new version works good. But I can't find the download button which is the arrow button beneath the youtube vedio. there is just hollow space but it works anyway when I click hollow space.

Is there any way to set download directory before I download video? I try to set directory on setting but it doesn't work.

Liked the old version better. was much easier and it used to download both video and audio files when I click. can't find how to get it work this was again no matter how hard i try.

Best addon when it comes to downloading YouTube videos. However, it requires you to download external files to make it fully functional.

:(

This is very useful addon for me.
thanks

Cannot detect url_encoded_fmt_stream_map or adaptive_fmts.

Hope You can fix it

Excellent add-on, and compatible with the new Firefox 57+ technology too... I agree with Rahoul, this is the last YouTube downloader you will try, there is no need to continue searching. I can't realize living without this gem. :-)

Tried a dozen of YT downloaders for Firefox. There was just one that was close to this one, but not close enough.

Tried this on two pcs (same os & FF version). One works fine, the other downloads the two streams but is then unable to find the downloaded streams! Rechecked the limited settings, reinstalled .. zilch. Only other difference - on the one that works I got a firewall exception request which I allowed. No alert on the other one. Suggestions anyone???? Short of manually merging the streams using ffmpeg.
The support page has several posts but no replies from the author.

Your search for the more apt youtube downloading tool ends here :)

Usado en Firefox Developer Edition 57.063 (64-bit).
Cuando se elige una calidad de bajada en el Download Panel, al terminar de bajar el archivo desaparece, no guarda nada. En cambio hay que hacer "Guardar enlace como", elegir dónde guardar y entonces sí lo baja y guarda. En versiones anteriores se podía usar el procedimiento descrito primero.

After looking at numerous other Firefox57-compatible video download tools, this is the first I've seen that accesses both audio and video streams and combines them into one file. It uses the well-known FFmpeg codecs, which needs to be installed and location inserted in the options dialog.

Bello

This is the best plugin to download from Youtube. A lot of formats, works really well - please keep updating!

Working Perfect for 8 years

If i try download a movie where is already only one file "audio and video, like in 720p usually" it extracts the audio, save this file and delete the movie one, and keeps the audio file only, not the video, if the quality i choose it's in separated files "audio and video, like 480p" works nice.
