uma das unicas a funcionar , obrigado desenvolvedores!

I have been using this add on for past few years most trusting add on

Okay, so I enabled Post processing (if FFmpeg is installed-it is) convert to MP3... it doesn't do that. Which is why I wonder if it's right to have "-loglevel error -i %input -q:a 0 %output" in the MP3-conversion field or if there's something else I have to change.

You just made my daughter a very happy little girl :)

Now it is fixed the error. Thank you for the updated.

Works great,
im missing one option in "Postprocessing if ffmpeg installed" [ convert to wave ]

I friggin love this plugin.

5星好评啊！一直用的都挺好的，但是现在有些视频提示我“signaturelocal:cannot resolve signature;3” ，不明白为什么，希望尽快解决吧！

5 stars praise! I have been using it very well, but now some videos prompt me "signaturelocal: cannot resolve signature; 3", I don't understand why, I hope to solve it soon!

Kadang error saat download

Good

Love this app but from 24-1-2020 I have a localSignature error. Please Fix it!

Love this extension but like others I am too getting the error - signatureLocal: cannot resolve signature;3

EDIT 1-25-2020 11:25AM Eastern
Just one day later and this is working again. YAY!! feller ROCKS

signatureLocal: cannot resolve signature;3

Was awesome, now it does not work at all. I'm sure it will be updated so keeping the 5 star rating, for now.
Not a new problem, YT changes stuff all the time. This developer keeps changing his app to comply with the changes.

No proper funktion since the last days ... HOPE for update soon!?

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

All of a sudden, it flat out doesn't work. I guess either a bug was introduced or Google eliminated direct downloads period, not just in their own store.

Have uninstalled and reinstalled the extension, cleared cache, refreshed Firefox, etc Still no joy.

Would rather not be forced to pay for a separate downloader to get the functionality I had as little as a day ago.

UPDATE: 05/07/2020
Now the new error is "Type error for parameter options (Error processing url: Expected string instead of undefined) for downloads.download.

Went backwards to FF 75 from 76 and the same error.
