it discovers audio, but unfortunately sucks with blob:https//... video handling.
in other words, it tries to do things VLC does best way.

Youtube = no work nuff said it's crap addon

now it finds nothing
FF 132.0.2 x64

Находит, но скачивает только то, что загрузилось и к тому же отдельными файлами, это же можно сделать штатными средствами, так зачем перенагружать браузер ненужным расширением?

Did not work

Doesn't work at all - nothing on a toolbar.

por los comentarios no vale

Didn't work on Youtube but worked like a charm on whyp.it

It does not detect audio on the page.
Amen.

Does not detect audio on lernen.goethe.de

Doesn't work with Vkontakte. That's sad...

Breaks down video into multiple few second videos without sound and multiple audio files. Not sure how this would be useful to me in any way.

It do can download the videos from pornhub.

Doesn't work on Youtube, Soundcloud or Xvideos. On youtube it sees nothing, on soundcloud it sees the individual streaming audio bits, but not the whole song and on Xvideos it does the same but with video, no full download link anywhere. So sorry but this is completely useless to me.

In contrast Ant Video Downloader does see the full video download link and does not spam me with 400 bits that i have to scroll through.
I've submitted a bug report, if the author contacts me after fixing it i will try it again and give it a second chance and re-rate it.
