No button, no harm, no foul. Not sure what stopped the extension from working, but no impact on browsing.

too slow!

It works but holey smokes is it slow, you had better not be in a rush because this app will slowly drive you crazy it's so slow. I normally give up on most conversions before they are done.

Easy to use but too slow and gets stuck on 99%.

Converts to m4a not mp3, BUT it needs only read page permission on youtube.com, meaning that it's one of the extensions that I can trust.

Antes servía, no se que le pasó

It used to be a great add-on until this morning I found the button doesn't appear.

This extension doesn't actually convert or download anything. It just redirects you to another website that does the conversion and downloading and there are plenty of sites that do this, which makes this extension redundant. And I did get a scamware pop-up ad at some point, though I'm not able to confirm if it's from this extension or the associated website.

"Error: Could not generate download URLs. Please, try again.

FFS, first time using it and I get that. Great.

The Service is spotty, however when it does work it is great.

Does its work but has annoying malware advertments

I always get 504 gateway timeout

Funciona bem! Mas tem que ficar esperto com os AddOns. Quando as conversões estão sendo feitas são abertas muitas outras páginas e algumas com downloads de softwares suspeitos e falas mensagens de atualização do navegador. Não aconselho para quem não tem experiência com as porcarias da internet.
