You should see an pop-up block icon at the right end of the location bar if pop-ups are blocked and the notification bar at the top is hidden.

I made sure that my add-on bar was on, and I'll see if I can catch it.

Thanks, Chuck

That pop-up block icon is no longer at the bottom of the browser (Add-ons bar, previously the Status bar), but now appears at the right end of the location bar.

Location bar = URL bar = Address bar = where website addresses are typed and displayed

Ah...OK thanks guys.

Chuck
