Blocking Pop-Ups

Blocking Pop-Ups

Pop-up windows are the windows that open when you click on something on the Web, and sometimes they just seem to open themselves. They have become a standard practice on the Web, and some Web applications use them legitimately. For example, MyFAU’s e-mail and calendar clients open via pop-up windows. But pop-ups can also be a result of spyware or adware, and, perhaps most dangerously, can also be used by malware to gather personal information. A good rule of thumb is never enter your personal information in a pop-up window.

The good news is that you can block pop-ups, but blocking all pop-ups can be dangerous because some Web applications use pop-ups to provide information or functionality. Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, Apple Safari, and other browsers have pop-up blocker options in their tools/preferences. (See information below on setting the pop-up blocker in these applications.)

Blocking pop-ups can greatly reduce the annoyance and damage from spyware, but you need to be aware that it can also decrease the functionality of some programs. Turn the pop-ups off as needed. With most pop-up blockers, you can temporarily override the blocking by holding the control key when you click or you can identify sites whose pop-ups you will accept (for example, accept pop-ups from MyFAU and Canvas).

Also keep in mind that you should review your pop-up settings if a program isn’t working as you would expect, especially if nothing happens when you click on an icon that should open a window.
