Firefox and Popups

People who have been using Firefox know that the web surfing experience is so much nicer, but there have been grumblings in the geek circles about the increasing amount of unwanted popup windows Firefox is missing. As the browser has grown in popularity, so has interest in finding ways around its popup blocker.

Well good news recently came from this guy, who found a way to block one of these newer popup techniques.

Turns out that by using the Flash plugin, creepy web site owners could generate popups that Firefox couldn’t block. Not anymore.

1. Type about:config into the Firefox location bar.
2. Right-click on the page and select New and then Integer.
3. Name it privacy.popups.disable_from_plugins
4. Set the value to 2.

Hopefully Firefox developers will build this into the next version.

Thank you, Pete Bevin!
