It can not block every cookie which is a bit weird. It does what it has to do that is perfect enough for me to a certain point. It does slow down pages a bit not by much but neither i care for that. All that matters is it works for what they wanted it to work and even tho it does not work on every page is a bit of a problem when you cant block certain pages to create those spyware cookies... The sad part is is not getting new updates no more...

Makes page loadings hang with setting 'on leave' enabled. Also no longer maintained as stated at github.

This extension is my beloved! Logical and clean UI! So much power with so little annoyance!
