I disabled all popups in Firefox by going to about:config > dom.popup_allowed_events and removing everything. Unfortunately, now I have to allow Flash every time, which was not my intent. I didn't think it was a popup. How can I re-enable Flash? I set it to Always Activate in Plugins, but config seems to be overriding it. Also, Flash, when enabled, goes really slow then stops. I reset Firefox but that didn't help.


Use the following to enable Flash:

about:config => plugin.state.flash = 2

The flash plugin has 3 states:

  • off is 0
  • ask is 1
  • on is 2
