A few weeks ago we mentioned the yellow exclamation point in Gmail that prompted us to switch from Chrome to Firefox to Opera. A reader said he gets it too and wonders why. We finally have the answer.
Every web address these days begins with “https” rather than the simple “http.” (The “s” is for “security.”) If you have a browser add-on that still uses the simple http, Gmail flags it. It can be quite annoying, even causing your email to freeze, but it appears to be harmless. In our tests, simply uninstalling Google Chrome and reinstalling it without any add-ons fixed the problem.
