Stop using Internet Explorer

Internet Explorer is dead.

If you like Microsoft products, you can switch to the new Edge browser.

You can download one of these modern, fast and secure browsers.

Internet Explorer has been deprecated by Microsoft, it is not supported anymore.
Internet explorer is not secure! Your private data is in danger: from your messages to your bank accounts and files on your computer, you are risking to lose everything!
All major websites do not support Internet Explorer: Facebook, Google, even Microsoft itself blocks access to their services if you use IE.
Internet Explorer does not support modern encryption standards, you won't be able to open any website soon.
IE is very slow. In comparison to modern browsers, IE lags behind.

Your desire to satisfy everyone is not good, it's evil! By continuing to support IE you are putting IE users in danger by allowing them to browse your website seamlessly.
Polyfills are evil! Each time you include a lot of code to translate modern javascript to a simpler version IE can understand, you are slowing down your website drastically.
