This add-on is basically dead.

Better than the original, no private data collection.

It used to work perfectly on youtube (on private browser) but now I'm getting "Your watch history is off" page followed by a refresh a few seconds later before landing on the homepage. So the annoying part is I have to wait 5 seconds for the page to be refreshed to start typing on youtube

It simply doesn't work. I am using No Script as well and I deactivated it thinking there could be some improbable interferences, but this add on still does not block any cookie.
