This plugin, is fake, as it does not limit the data usage or even stop the downloading of Youtube videos.

The video parts are still downloading in the background, just the overlay image, is shown on top of the video, hiding the video content.

Shouldn't request permission to read data on ALL the websites, since it works only for Youtube. There are other extensions who do that. Uninstalled immediately.

Does what it advertises. Unfornately i can not use the controls to fast foreward or rewind, change volume or anything else than just listening after the page loaded.

I changed my mind about downloading this add-on after it asked for permission to read the data of ALL the websites I visit. This sounds suspicious as this add-on is for use on YouTube.com only.

data usage does not differ , it uses a lot of data usage ! do no use.

I suggest to notice this addon is not for Android. This help to avoid wasting time to try on Android.
Thank you.
