I actually made that for Chrome. It worked. I got disheartened that no one ever downloaded it from the store so I destroyed it. All it did was pop up a Yes&#x2F;No alert that said, &quot;Really?!&quot;<p>It also had a back off that was configurable. There were times when I was doing actually productive research that the constant questioning was annoying, especially intrawebsite. So you could delay the next request for N minutes based on a configuration.<p>Other sites were white listed. They were low volume, low distraction or high value like google.com.<p>In the end I destroyed because it felt like another failure. No one wanted it. So I took that as a personal rejection. It could just be that I did a poor job of marketing it. I might try making it again, but for Safari since I&#x27;ve recently changed.
