this actually works.

I tested it with a 6 min video on 360p. Sound only: 6.41 MB, with Video: 17.85 MB.

I visit relatives who only have internet access through Hughes Direct TV. If I play YouTube videos, I eat up their data allowance. Normally, I'm not interested in the video content and just listen to audio while performing other tasks. This app is perfect for listening to lectures, music etc.

Does exactly what it advertises!

Great when just the audio matters

Great idea behind this add-on.
But here's the problem - it doesn't work on a live streams, like, 24/7 radio.
When i try to enable this add-on on a stream there is no video and no sound at all.
I don't know if this is a issue on my side or internal problem of the add-on

Ca défonce !

Thanks dude for creating this gem. Keep up good work.

Vixeolar engelleniyor perfect. Data kullanımını düşürüyor. Herkese tavsiye ederim. Yapan arkadaşların elleri dert görmesin. Teşekkürler

Works great..

as said, only downloads audio stream... thanks

Actually it works. Don't know about net traffic, but I needed it for a very old eeePC which would go crazy hot. Now it is just fine.

Checked the source code, it actually downloads only the audio stream. The video stream is removed ( not downloaded at all ) from every stream that is played when then extension is activated. Confirmed from the network pane.

Loved that I can turn it back on while watching a trailer or news. With the extension turned on my laptop lasts significantly longer. The data consumed by youtube has also decreased a lot.

What would have really helped was if it could cache / store most frequently watched youtube videos. That would have really reduced data consumption.

Very useful to people with data caps / FUP. Do hope it updated when youtube next changes their site. Keep up the good work.
