We know the annoying pop-ups advertisements are all over the World Wide Web when we are surfing websites. Most pop-ups are generated by Javascript and most browsers including Internet Explorer 7 and above has “pop-up blocker”. Since pop-ups are easy to “kill”, pop-unders are then being introduced. Normal pop-up blocker embeded in the browser is not able to “kill” pop-unders. This is because, pop-unders are made available by Abode Flash Plugin!!
What is pop-under anywhere? It’s the annoying online advertisement which appears “beneath” / behind your current active browser. Once the advertisement is launched, it will automatically open up a new window, showing ads without really disturbing you for the time being, until you close your current browser. (then you will have to close those extra meaningless windows)
If you are using Firefox, you can disable pop-unders in just few steps!
In your browser URL, type about:config and press enter.Then you will see something like this, if you are using Firefox 3.
This is something new in Firefox, and it generates random title like “Here be dragons!” or “This might void your warranty!”. Interesting, right? Click the button to continue.
Right click any where and select New > Integer with the preference name of privacy.popups.disable_from_plugins and enter 2 for the value. Close the config window and you’re done.
Some other 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.

Talking about Firefox 3, here’s something very interesting. (Thanks Darren, for the info) If you haven’t know, make sure you try it out in your Firefox 3 browser.
Type about:robots in the browser URL and see what you get!
Welcome Humans! Cool, eh? Out of curiousity we sure want to see what is coming up next, so we click on the “Try Again” button and we get this:
Nothing change except for the button “Please do not press this button again”. I PRESSED! I think most of us will still press it. Did you? 
Are you still not using Firefox? Start using it now.
