If you’re a web developer, you know how to close open tabs on your Android device. But what about developers who use Android for their day-to-day work? How do they close open tabs without having to remember every single command? There’s a way to close open tabs on Android using the built-in browser on your device. Just open the Browser and type “chrome://flags/content_security_policy” into the address bar. Then click on the “+” button to add a new flag. The new flag will add a security policy to Chrome that will prevent your tab from opening again until you enter your password. This is an effective way to close open tabs without having to remember every single command.
