Without disabling the javascript. Is there an add-on of some sort out there that allows you to just block AdSense in your own browser? Thanks.
This is on your site? Put a bit of logic in there that says that if you are logged in as an administrator etc then show a placeholder and not the ads. I have sites where I put the site into debug if the user is at a particular IP address - annoys my husband but saves the other admins from seeing my debugging efforts. They're real admins while I'm just the techie. In WordPress the google analytics plugin puts a placeholder in when the admin browses the site so that those hits aren't collected but the admin can be reassured that the plugin is working.
