not only this extension pops up all the time to ask me to pay for it, but among all the ones I tried, this is the only one that will block any website loading for two minutes on Linux installed on a Chromebook

good

Works great, right up until it fails completely!

Good Extension and its remove all ads on youtube

Best addblocker only one site detected me

It used to work great and blocked all ads. However, now I'm seeing ads on a lot of sites such as Yahoo email and news. It will block it again if I tell it to but once I click on an email or article the ads return.

Very good very user friendly.
