I recall that previous versions of TBB came with Noscript, but with javascript enabled by default. Since then, it would appear that the settings for Noscript (TBB v3.6.4) have been modified and javascript is now disabled, as tested with http://www.isjavascriptenabled.com; https://panopticlick.eff.org
I am curious, however, about the security of the current default configuration and what vulnerabilities the browser might plausibly be susceptible to. Are there any other adjustments to Noscript settings that might be beneficial without significantly affecting browser functioning?
(I am working on the premise that the default Noscript configuration that the browser ships with may not necessarily be the most optimal, as was the case with previous releases of TBB.)
