“Click&Clean” is a Chrome Browser extension that I’ve used for years. It does lots of things. One of its many privacy functions, (snicker), is it tells you if you are logged in to Google, Facebook or Twitter. As the app states regarding that particular feature that's specifically just for the three account sites states: “Are you logged in? What does this mean? This implies that any website can obtain quite a lot of information about you. If you see your profile picture above, then it doesn't take a magician's trick to determine your public profile and learn more about your interests - for example, by using Search by Image service.’ ‘Therefore, we do not recommend you to surf on questionable websites while you are logged in to an account. Do not go to any other websites while banking on the internet!” I’ve always made it a point to periodically check and make sure I wasn’t logged in to Google, Facebook or Twitter unless I wanted to be. If I was I took steps to log out and verify with the extension. It has worked fine for a couple of years. Now, no matter what I do I cannot according to “Click&Clean” log out of Facebook. The app shows me always logged in. This remains true even if I clear all cache including all cookies, locally stored data and manually check my Facebook account to make sure I am logged out. Naturally, I make sure both the extension and the version of Chrome is always up to date. This issue has been going on for about four to six months. For me, it's proportionally more of an issue of curiosity than privacy. What’s the deal?
