Disabling JavaScript in chrome

A simple way is to

1. Open the console by pressing F12
2. Click the hamburger icon on the right
3. Go to "Settings"
4. Under "General" check "Disable JavaScript"

Since Chrome 16, there is an extension named Quick Javascript Switcher that turns Javascript on/off on the fly.

If you're using Chrome on Windows then you can create a copy of your Chrome shortcut (rename it to Google Chrome no JS, for example). Right-click on it and select Properties. Add -disable-javascript to the end of the Target field. The end result should look something like this:

C:\Users\UserName\AppData\Local\Google\Chrome\Application\chrome.exe -disable-javascript

When you open Chrome using this shortcut then JavaScript is disabled
