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.

Never blocked a single ad. Cannot understand what this thing does.

Use to be great, but now I'm getting white masked coverup ads for grammarly. At the start for every video.

Glitchy - Video stops to work, and browser reports about some script error. Removed this app after one day of use.

doesn't work anymore

New update rued everything. changed all my settings to default, would not accept importing my old ones, and now half the features don't even work, like auto resize on or off does noting, and it's the same story for volume control. Yes I have tried restarting, and reinstalling the extension, no it didn't fix anything. This has been my favorite add-on for as long as I can remember please make it functional at least! (and no it's not my PC 4.3GHz6core/32gRAM/980Ti if it is who tf is the app for?)
