+
+<p>
+We configure NoScript to allow JavaScript by default in the Tor
+Browser Bundle because many websites will not work with JavaScript
+disabled.  Most users would give up on Tor entirely if a website
+they want to use requires JavaScript, because they would not know
+how to allow a website to use JavaScript (or that enabling
+JavaScript might make a website work).

+
+<p>
+You can configure your copies of Tor Browser Bundle however you want
+to.  However, we recommend that even users who know how to use
+NoScript leave JavaScript enabled if possible, because a website or
+exit node can easily distinguish users who disable JavaScript from
+users who use Tor Browser bundle with its default settings (thus
+users who disable JavaScript are less anonymous).
+</p>
+
+<p>
+Disabling JavaScript by default, then allowing a few websites to run
+scripts, is especially bad for your anonymity: the set of websites
+which you allow to run scripts is very likely to <em>uniquely</em>
+identify your browser.
