Microsoft’s Internet Explorer is, by all means, an outdated piece of software and, as such, it shouldn’t (if not necessary) be relied on. Instead of Internet Explorer or other browsers, consider switching to Opera which allows you to do everything you can on IE, but with so much reliability and versatility, in a private and secure environment.

If you are in a dire need to use Internet Explorer features, you can add the IE Tab extension to simulate it on Opera.Feature-wise, Opera is based on the Chromium open-source platform using the Blink layout engine, so it supports all Chrome extensions. But, in comparison to Chrome, there’s no fear of privacy intrusion, thanks to its countless anti-tracking built-in tools.
