Can't block pop up ads on Safari
I did every way on apple support to block pop up ads on Safari but nothing worked. I did choose "block pop-up Websites" on the setting of safari, check the expansion, allow to get warnings for unverified websites, restarted the MacBook and update to the newest MacOS but nothing worked. I also try to figure if there's any virus apps but for sure there is not. Because I just reset this MacBook 3 days ago and the only App that was installed till now is Discord. Mine is MacBook Air 2020. How can I fix this problem now?
Thank you for your help in advance
