Hi, I use Firefox with Firefox Multi-account containers and temporary containers extensions. While I was setting web pages into that containers couple of times I went to Firefox options manage data button and I noticed that every time I visit some page adtidy.org cookie is created (becomes active). I thought it is some sort of ad cookies but when I go to cookie address it direct me to AdGuard page. That seems strange to me or am I missing something? Why is browser extension creates a cookie? This is the first time I am seeing this, I have some other extensions but none of them make cookies. What does this cookie do?
