Great! Rated 5 out of 5 stars
Contrary to what PR-Imagery (below) says, it works very well, and I have never been unable to log into sites after enabling all (session) cookies for a site.
Be sure to click on "Cookie Access => Site Level" too to see whether you don't have any sub-domain cookies blocked, as those can still prevent you from logging in.
The menu could be clearer, because, after a month, I know perfectly how to use it, even though I *still* don't understand some of the things the menus say, and I find that I have to go through several submenus every time.
I still don't understand what "use 2nd level domain names" does. What are those? And how do you mean "use"?
The icons are confusing. Only the devil icon makes sense; the others I find impossible to remember even after a month.
