It's simple and great, it just works helping me stay focus while working.

Bad performance on top of privacy concerns

love it . it block such site that i don't want

aside from info i found after downloading about info selling (which i do not know the validity of). i put a site in my blocklist. i then realized i could change it to be a whitelist. so i remove the items in the blocklist, add some sites to the whitelist, and then switch tabs to find the whitelisted site is blocked for not being on the whitelist. ok, i'll just use the blocklist then. so i switch to blocklist and remove the site. and it then says the site is on my block list. neither of these things are true. i try to go to mozilla addon site to read more to resolve it. it is not whitelisted so i cannot connect, despite me being in blocklist mode. i know i am not that incompetent here so i am forced to assume either the addon is inherently bad or has some absurdly specific bug that renders it 100% useless. but either way i have no reason to use it
