Why install some time limited extension (I suppose you will have to pay after 24 hours?) when the best ad content blocker - uBlock Origin[1] - is free and open source? I've been using it for years and it simply does the job well and it's very light on the system. I've browsed CoinGecko with it for the past minutes and no popup appeared. I would advise you to uninstall AdBlock and just install uBlock Origin and try it out for a couple of days.
