What are Adblock cookies for?

The solution is to delete SiteSecurityServiceState.txt, create a new one and set it to "read only". There were also cookies created by Flash Player despite I set it up to not store data on my PC: you also need to set up an online panel on the Macromedia website. From what I understood the fact that Firefox can't delete super cookies is a bug that still have to be fixed, but I'm not sure about that...

I found out it's caused by super cookies in SiteSecurityServiceState.txt, these cookies can't be deleted by Firefox.

My Firefox settings are such that cookies should be deleted when Firefox is closed, except for a few exceptions. But I've noticed that CCleaner finds some cookies (Options > Cookies) that shouldn't be there (while Firefox is closed) and that are not in the exceptions (of both Firefox and CCleaner). Firefox doesn't find these cookies (Options > Privacy > Show cookies). These cookies all seem to be from websites I access with Firefox. I've cleaned with CCleaner but they reappear. I didn't select the Intelligent Cookie Scan. My Flash Player settings are such that no website can store data on my PC. I have: - Windows XP - CCleaner 5.11.5408 - Firefox 42.0
