Edit: it is working fine with Firefox 76.0.1
thanks for the reply

Was working great, but just stopped working with Firefox 76.0.1.

ich haben seit 2 wochen download und heute geht das nicht mehr dann haben ich das gelösche dann kann ich nicht mehr download.

Just Left VideoDowlnloadHelper for trying to charge for the most used format. I am loving this BUT way too many permissions. The check for this is that you can "Disable" under "Add-ons" in Firefox until you need it. The key of course remembering you have it to "Enable." Thank you developers.

Usually a great add-on, but it can't see all YouTube videos. For instance not this: https://www.youtube.com/watch?v=ToXNDnBUa5A
It's also a bit worrying that it want permission to access and modify almost everything.

Addition Jan 1, 2020: I will give your app one more star because I believe you when you say you have fixed the problem. But I installed the other add-on "Download Video & Flash", so I haven't tested your new version... ;-)

gostei mais n sei como fazer pra baixar somente o áudio dos vídeos.

I like this add-on but.... I use Firefox nightly 70 64 bit for windows 10 1903 laptop and... I can't get the dropdown menu to show up like it use to.
