It's a decent enough blocker, tried it after a re-install. But ditched it and reverted to Ublock origin, with Ublock you can select extra blocking. First I noticed with this blocker was sites saying I'm using a blocker, notably outlook email. Back to Ublock and outlook has just let me go where I wanted, no messages about blocking. Ads are annoying but sites reminding you of your blocker is a nuisance too.
