If your talking about it being in the Adobe settings. Just click delete all websites. Set the "space" to zero. Click "don't ask again'. Do this under both storage sections. I have no idea why people think it has to have space available. It doesn't. Mine never has any sites, or storage, ever (it stays at zero settings/space). Everything you see in those sections are nothing but cookies (that are not needed), and trackers. Install Ghostery and Adblock if you don't already have it. I use IceDragon, and set it to "private browsing" (it never keeps any cookies from any site, that way). I only have to pause adblock/ghostery when I do surveys or videos.
