Internet Explorer (IE) is better than it once was, with page-loading speeds that rival the competition, and optional privacy features that beat them. And yet, it doesn't always play well with non-Microsoft products – so forget using the latest version, IE 11, on a Mac, or any version on an iOS device. To be able to sync browsing histories and bookmarks across essentially any device, creating a more seamless experience whether you're tapping on a keyboard or a screen, try Chrome.
