You can go back to 1993 and turn your web application platform (a.k.a browser) into simple document reader by disabling javascript (+ plugins, whoever keeps them enabled anyway). Good luck with that.
Oddly enough IE is the browser that seems to keep the option of disabling Javascript buried the deepest within their context menus. In Firefox it's just Preferences -> Content -> uncheck "Enable Javascript" (I do this to avoid NYTimes' paywall, lol) but in IE you have to scroll through an exceedingly long list of checkboxes that's a couple levels deep into their menus to find "Disable active scripting" because they still refuse to call it Javascript. I always forget where it is and have to hunt for it every time. Obnoxious.
You are suppose to set the security level of the Internet zone to "High" (the default on Windows Server), or add the sites needed to the "Restricted Sites" zone.
