The problem is that you have to manually type the cookie addresses (like in the first image) into "Manage Permissions pop-up Box thingy" (under Setting-> Privacy&Security-> Cookies and Website Data) which gets really annoying when you visit a lot of different websites or you are testing which one u really need and which u don't,

Also i would like a way of allowing cookies only on selected sites(maybe another button for this)

I am blocking all cookies and only manually allow cookies that I really need. The problem is that you have to manually type the cookie addresses (like in the first image) into "Manage Permissions pop-up Box thingy" (under Setting-> Privacy&Security-> Cookies and Website Data) which gets really annoying when you visit a lot of different websites or you are testing which one u really need and which u don't, i would really wish for an "Allow this cookie" button (like i tried to draw in the second image) especially since there is already one for clearing. Also i would like a way of allowing cookies only on selected sites(maybe another button for this) but i don't know if this is even possible or if a website, once it has set its cookie, can still get access to it on another website.
