Google Chrome extension - how to turn JavaScript on/off?

Question

Is it possible to turn JavaScript on/off with a self-made Google Chrome extension?

For example, in Opera browser, there are simple possibilities to do that with widgets, user-made buttons, etc., but I didn't find any solutions to do that in Chrome (my first source was the official Google Chrome extensions' documentations).

A strange aspect is that I need JavaScript to run the extension itself...if I'm able to turn JavaScript off with an extension, can I still use JavaScript in my extension after doing it?

Edit:

It's already possible to do it via chrome.contentSettings.javascript!
See this example which shows how to use it (Quick JavaScript Switcher extension, which mlb linked here).

Answer 1

It's now possible with the ContentSettings API,
and there is an extension named Quick Javascript Switcher that turns on/off javascript on the fly : https://github.com/maximelebreton/quick-javascript-switcher

QJS on the Chrome Webstore : https://chrome.google.com/webstore/detail/geddoclleiomckbhadiaipdggiiccfje
