The Google AdSense Terms of Service warn against clicking on ads on your own site. Google AdSense Program Policies

Please note that clicking on your own ads for any reason is prohibited, to avoid potential inflation of advertiser costs.

However, sometimes I can’t stop myself, I forget I’m on my own site, and just want to click them so much. (Too bad the other viewers of my sites are not so excited, otherwise I’d have retired) It’s even worse if I’m looking at one of my sites on my kids computer, someday I’ll forget to close the browser window, and a kid will illegaly click me out of AdSense, no more commissions, no more money.

So I’m pleased that someone came up with a great solution - it’s for FireFox only, but why would you use any other browser?

Prevent accidental clicks on your own AdSense ads

This is an addon to Greasemonkey, so if you need that, install it first.

Once installed, it will require you to entire your AdSense ID, so it will only blog your own ads.Remember to install it on all the computer at work or home (and laptops also) that anyone can use to access your sites. Google is pretty smart and it will track you down - and saying my friedn at work clicked my ads by mistake won’t get you back in the loop.
