Controlling Popups

What are Popups?

Pop-up windows, or popups, are windows that appear automatically and without your permission. They vary in size, but usually don't cover the whole screen. Some popups open on top of the current Navigator window, thus popping up, while others appear underneath Navigator (popunders).

&brandShortName; allows you to control both popups and popunders through the Popup Windows preferences panel. Since popup blocking is turned off by default, you must enable it to prevent popups from appearing in Navigator.

When blocking a popup, &brandShortName; can be set up to play a sound, as well as display an icon Popup control
  icon in the status bar. You can use this icon to add a website you're viewing to an exceptions list so that the site is allowed to again display popups.

Blocking popups may interfere with some websites: Some web sites, including some banking sites, use popups for important features. Blocking all popups disables such features. To allow specific websites to use popups, while blocking all others, you can add specific websites to the list of allowed sites. For more information, see Privacy & Security Preferences - Popup Windows.

Blocking popups doesn't always work: Although &brandShortName; blocks most popups, some websites, even when blocked, may use other methods to show popups.

Allowing popups from certain websites: After you've enabled popup blocking, you can still allow specific sites to display popups. Browse to the website, and then from the Tools menu, choose Popup Manager, and then choose Allow Popups From This Site.

The next section describes how to control popups through preferences and through the popup control icon.

Privacy & Security Preferences - Popup Windows

  1. Open the &brandShortName; Edit menu and choose Preferences.
  2. Under the Privacy & Security Preferences category, click Popup Windows. (If no subcategories are visible, double-click Privacy & Security to expand the list.)

When a popup window has been blocked
