I recently blocked reddit.com using the screen-time feature on my Mac OS. But I've noticed that when I am browsing certain sites, like retail sites, I will receive pop-up windows (as pictured) that say that firefox is trying to access a secure website. I've deleted the browsing data related to this site; I've deleted the cookies also. I'm not sure what else to do to remedy this... It's gotten so bad that I will get the pop-up with every click on certain sites. Every new page generates a new pop-up. Please help!
