Firefox Tip: How To Stop Flash Popups

Firefox has a decent enough popup blocker built-in, but like most blockers it doesn’t stop Flash popups. To fix this do the following:

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

The possible values are:

  • 0: Allow all popups from plugins.
  • 1: Allow popups, but limit them to dom.popup_maximum.
  • 2: Block popups from plugins.
  • 3: Block popups from plugins, even on whitelisted sites

      Doesn’t seem to work with click triggered flash popups like the one shown in this example. I can’t find anything to stop things like this.

      Ya doesnt work anymore… have ‘slide ons’ popups  that you have to kill manually (find the hidden x somewhere). I think the flash update undid the  trick here.  I keep sending complaints to the browser makers that their pop up stoppers dont work… maybe that will work eventually.
