Default Firefox about:config hack for popups

One of the sites I frequent (which shall remain nameless) had a persistent popup...the minute I placed the mouse cursor in the search bar, a popup opened up and the page I was viewing simply became blank, I then had to press the back button to view the page I was originally viewing. When I viewed the page in IE 10, the popup was blocked and IE displayed the message that it was blocked. I got curious, dug a bit deeper and found this about:config firefox entry for popups:

http://kb.mozillazine.org/Dom.popup_allowed_events

I went to about:config and searched for the string "dom.popup_allowed_events", removed all the entries (change click dblclick mouseup reset submit). This will disable all popups (good, bad and ugly). All popups blocked, you can of course whitelist the sites for which popups should be allowed. Happily ever after!.
