I was using Charles earlier to monitor some HTTP requests and noticed that every few seconds a request would show up trying to ping 127.0.0.1 (localhost) on port 7682. This was odd so I did a quick search and found that I had actually tweeted about this approximately 112 days ago — and had completely forgotten.
So if you see this, simply disable the Adobe Edge Inspect extension in Chrome in the Extensions settings.
Let's see if I remember this time.
