Diễn đàn hỗ trợ Firefox

currently using FF; I do NOT have any ad blocking software installed ( that I know of) I searched my computer for the word block, and it did not show it anywhere. I also have Mozilla Seamonkey installed, but not using it. Each time I visit a news website I get a popup that claims Im using an ad blocker. I have searched all those adbocker pgms on my computer and none exist. Why am I getting these pop ups. I think I also checked the AVG pgm, but didnt see an adblocker there. How do I fix this situation from continuing

I just started getting an annoying ding/small pop-up window that appears to be a link to various ads . . . I would like to get rid of it.

I assume it is FIrefox, as it started happening after my most recent update. I also assume there is a setting I can use, but I don't see a settings icon in Firefox. <Sigh>

Possibly it only pops up when I'm using Duck Duck Go, but I'm not sure about that.

Sure need some help here . . . much appreciated.
