I am sorry but there is a persitent cookie linked to this addon.

When i start a session and i go directly in my setting i fond a youtube.com cookie.

My FF clears cookies at the end of the session so there should no cookie at all at the beginning of a session.

I couldnt find info about that youtube.com addon cookie on the developer website.

Thanks for explaining why this cookie is created when the browser loads all the addon and when i start to use youtube.

Best and most used plugin, extension, whatever. This developer has inspired me to understand what is going on in a machine. I am just not sure where to start.
Best browser plugin that I can't afford. I wish I could figure out how to pay a few bucks at least.
Edited/updated review. Still the best addon ever created for youtube. I find it to be essential to enjoy anything I view on youtube. I most likely wouldn't use youtube much at all if this addon were to go away/disappear. It gets put in my browser just as I Ublock O or my password manager. The Enhancer has more functions than I'll ever use and the parts that I do utilize make youtube basically painless to view videos on the site. I wont watch youtube without it. I dont watch youtube on my phone for the gigaton of ads that are on there. I quit watching TV well over a decade ago because of commercials.

The developer deserves more than I can give. If you can donate and you make the big bucks, please throw a $20 his way for me. Im on a very limited income and cannot afford to donate unless I have some pile of cash miraculously happened to me. Disability doesn't cover my bills all of the time.

Have a great day.

Please, add option: block channel trailer autoplay.

This fixes nearly all of the problems I have with Youtube's play system, my thanks to its creator.
