Trash & Spam folders need replaced. I make mistakes and sometimes delete the wrong items. Or, sometimes they've been deleted and later I find I need them. Now I'm unable to do that.
Also, I have found important emails in my Spam folder. Now when someone tells me an email with important documents or information has been sent and I can't find it anywhere, there is no Spam folder to check.
I've never had an Adblocker and suddenly I'm asked to remove it. What's going on?
