Background

To get around the default popup blocker, some sites use Flash or Java applets to open unrequested windows. This preference controls popups initiated by plugins.

[edit]

Possible values and their effects

[edit]

0

No restrictions on plugin initiated popups.

[edit]

1

Limit the number of plugin initiated popups to value defined in dom.popup_maximum. (even with popup blocker disabled)

[edit]

2

Block all plugin initiated popups. (whitelisted sites will still be able to open popups) (Default in Firefox 1.5 and above and SeaMonkey)

[edit]

3

Block all plugin initiated popups, even those on whitelisted sites.

[edit]

Caveats

Though rare, some plugin content produces legitimate (requested) popups. You will need to manually add such sites to your popup whitelist if this preference is 2.
