Pop Tarts, Not Pop Ups or Popped Collars

As you all know, our beloved Firefox does a great job of blocking pop-ups.
However, some still get through, despite the default settings
These little buggers are from flash or java/javascript applets.

Luckily, there is a pretty easy fix:

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

All of the possible values for privacy.popups.disable_from_plugins:
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’s pretty much it. I haven’t tested this on pages where you request a pop-up (e.g. clicking an item to open a new window), but I guess I’ll get to that soon enough.
