I've been trying to disable script using the IE Developer Toolbar for a while now. Well, at least I've wanted to for a while, but its was greyed out so I couldn't select it in the menu. Its a fine little menu, with "Disable" well placed between "Find" and "View", then when you click the Disable item from the menu, three options pop up: Script, Popup Blocker, and All CSS.

The All Css menu item worked fine, it would drop any styles applied to the page and show me the raw, unstyled HTML content. Yet for some reason the top two items were disabled.

I poured myself a fresh cup of coffee from the French Press sitting on my desk and thunk about it real hard. Then, I opened Internet Explorer, clicked Tools, Options and then navigated to the Advanced tab. Sure enough, the Disable Script Debugging options were selected.

I cleared the checkbox and restarted IE. Low and behold, I could now disable the JavaScript because it was no longer greyed out in the IE developer toolbar.

Drat!
