Internet Explorer 10 is designed to provide an add-on free experience, and will play HTML5 and many Adobe Flash Player videos without needing to install a separate add-on. Add-ons and toolbars will only work in Internet Explorer for the desktop. To view a page that requires add-ons in Internet Explorer, swipe down or right-click to bring up the Address bar, tap or click the Page tools button, and then tap or click View on the desktop.
You can view, enable, and disable the list of add-ons that can be used by Internet Explorer for the desktop. Add-ons you can manage include browser helper objects, ActiveX controls, toolbar extensions, explorer bars, browser extensions, search providers, Accelerators, and Tracking Protection settings.
