If you do not use the Firefox browser, this will not apply.

If you do use Firefox and have popup blocking turned on, some popups still get through. Even here on the forum, a pop(under) opens. Those can be stopped now too. It is the Flash-based ads that are doing it. You can disable Flash from opening popups by doing the following:

1. Type about:config into the Firefox location bar.
2. Right-click on the page and select New and then Integer.
3. Name it privacy.popups.disable_from_plugins
4. 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.

That will stop a bunch more popups that were sneaking in through Flash.
