Stopping Firefox Pop-ups

Like millions of other people, I am a big Firefox fan. I always find myself futzing with the program to make it run better, faster or become more usable. Although, over the last few months I have been noticing an increasing amount of pop-up windows being displayed.

Firefox supports pop-up window blocking, but for some reason these windows not getting blocked and they're being displayed. I am not against web sites that use pop-up windows to enhances its functionality. Although my views change when they're used for advertising. These windows are just annoying!

Well here is a tip to help prevent these pop-up windows from being displayed. It appears that some web site developers are leveraging the Flash plug-in to display these windows. Fortunately, there is a away to prevent this from happening:

• In the Firefox location bar, type "about:config" press the Enter key.
  
• Right-click on the page that is displayed, then in the context menu select 'New > Integer'.
• In the dialog box that is displayed, type 'privacy.popups.disable_from_plugins' in the field, then press the OK button to continue.
  
• Enter the value 2, then press the OK button to finish.

The possible values are:

• 0: Allows all pop-ups from plug-ins.
• 1: Allows pop-ups, but limits them to dom.popup_maximum.
• 2: Blocks pop-ups from plug-ins.
• 3: Blocks pop-ups from plug-ins (even for white listed sites).
