Here's a great tip from Pete Bevin (via Dvorak) if, like me, you've been seeing a rash of popup windows in Firefox recently. It turns out these are being generated via Flash and escape the popup blocking in the browser.
"It turns out that some clever people figured out that you could launch popups from Flash, getting around the Firefox default settings.
Fortunately, you can get around it:
-
Type
about:configinto the Firefox location 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."
I haven't seen a single popup since adding this to my configuration page.








1. Check out the Flashblock extension too... (http://flashblock.mozdev.org/)
