The following site has some tests for everyone who would like to verify their popup-blocking capabilities:

Firefox's popup blocking feature alone doesn't get the job done anymore. But the code below in conjunction with Firefox works well:

Firefox popups

Like you, I love Firefox for many reasons, including popup blocking. So over the last few weeks I’ve been surprised to see occasional popups.

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:

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.
