Outdated Browser v1.1.0 is a time saving tool for developers. It detects outdated browsers and advises users to upgrade to a new version.
So, you’re tired of people visiting your modern website with an outdated browser and not doing anything about it. Maybe they aren’t “power” users, maybe it’s your auntie running a last century browser trying to see awesome CSS3 animations and transforms. Let the user know that’s an outdated browser, and advise them on a better one.
