I think it may be a good product; but, have anyone ever read what data this thing can collect from your browser??? The "red flag" I get about this product is that it can READ ANYTHING you COPY and PASTE. Think about this for a moment: how often do you "copy-paste" your keys on Steemit or any of its related Dapps? I'm not sure I want this "crawler" sniffing out my keys! Unless someone can prove me wrong here, AFTER reading for yourself on the Google Chrome Extension description, this may be a serious data breach app.
RE: refresh crawler - It helps you refresh any website how offer you want
