Removal of "Enable JavaScript" and "Load images automatically" in Firefox 23

Hi Klasse

I can feel your frustration here and completely understand it. There are
lots of reasons to test a site with JavaScript disabled... corporate
proxies, noscript fallbacks, disable animations etc. Because "Disable
JavaScript" is a developer option we have made it available in the
Developer Tools option panel. Once it is set then all sites loaded into
the current tab will be loaded with JavaScript disabled.
