I cannot recommend this add-on. Cancelling a subscription appears impossible, short of closing the funding bank account.

The monthly payment receipt only has links for their payment partner, Paddle.

There is no pathway to login to the Adblock Plus account to cancel paid subscription. Trying to log into the Adblock Plus account returns an 'incorrect password' error, and no emails are received when the 'reset password' instructions are followed.

Do not install this, and if you have already installed it, do not pay for it. If they were confident that their product was good enough to keep you wanting more, they would make it easy to cancel the subscription. Instead, they have created one of the most difficult cancellation processes I've ever encountered.
