You are optionally notified when popup ads are blocked by a flash of the tray icon and Custom-Speakers sound (or PC Beep). It optionally blocks banner ads for faster surfing. The available options for the blocked ads are: empty frame; `[AD]`- a frame containing the text `[AD]`; a frame containing the ALT text of the banner image; or custom image.

It is enabled by default but you can quickly change this setting.
