  • Works well. Quick download. Doesn't ask you where to save the file, so it seems like it's not working. Check your Downloads folder!

  • Thanks for the update, now working again in Firefox.
  • does not work, "signatureLocal" message etc. Being logged in changes nothing.
  • Error: "signatureLocal: Signature cannot be verified". If you're getting this error you will need to update the plug-in. You may need to login to Google (owner of YouTube) also. Formerly, just logging in to Google was enough. Then it wasn't anymore for me yesterday. On the June 13th I downloaded the update for this plug-in and it worked. I was already logged into Google and I don't know if that's relevant. Good luck to you! It is a great plug-in when it's working!
  • good
  • Stopped working recently. Any file I download from YT stops immediately.
    Besides that, it is a nice addon based on ffmpeg.
  • This extension unable to download certain videos.
  • Best extension for get original files from YouTube.
