I tried this. It did not work for me. My problem is that it puts the message "Please disable adblock" where is the countdown is, instead of opening a pop-under ad tab.
It wasn't clear to me that "Easylist without element hiding" is the name of a new sub. After disabling Easylist and installing that sub, its working.
Thanks.
One doubt, though. How will lack of element hiding affect other ads/pages in general? Also, why did disabling that "^elemhide" rule in Easylist itself did not work?
why ? sadly there is an old bug (or ...it's due to how ABP is working with hiding filters) in ABP for firefox which can't manage always correctly the hiding filters
