I don't even see the button appear on the toolbar and I can't install it. nothing works

Best one out there. Just click the download panel and select whatever webm quality you prefer (720p is decent enough).
You'll get both the audio and the video files, cancel either one to cancel both downloads and download them again, it should download like x50 faster. You can even cancel the video download after the audio download is done, if you only care about the audio.

8/10 times download stops unexpectedly, even at the end - after 100s of MB came in already. No file can be found. Often, cannot detect the video file. This piece of crap needs a lot of fixes before going out.

MP3 decoding does not work

Скачивает со скоростью диал-ап, т.е. 46кб/сек. По сути скачка займёт больше времени чем потребуется на сам просмотр. И если что то оборвётся, то начинать прийдётся по новой. совершенно не практично.

Downloads run at 20kb/s Pathetic.

Ok, until it complains. download interrupted.
