I didn't find any flaws in the ad blocking probably because of other ad blockers installed beside this, but there's this one advertisement I've been getting and it's the Ad Block was updated tab. And let me tell you it's just one of the CRINGIEST ads on the internet!! My glasses are probably just old and dirty but all I see is "STOP SCROLLING AD-ON UPDATED NOW PLS BUY ME BEER PLS PLS PLS I LIVE IN MAMMAS BASEMENT !!!!1!!!11!! 😭😭😭😭😭😭😭" along with a bunch of PayPal options WHEN I'M LITERALLY IN THE MIDDLE OF WATCHING YOUTUBE VIDEOS! Welp, I'm very disappointed AND annoyed by these TAX COLLECTORS who are technically preventing other websites from monetizing, all while begging us for money. Pure hypocrisy! I just wish Firefox had an easy option to prevent all/individual add-ons from opening tabs automatically. I guess I'm going to uninstall so that I ACTUALLY get rid of the ads.
