I've been trying to extract unencrypted original scripts from a particular set of sites.
I tried to do it in parser file and JSScript file etc but it seems to extract some compressed form or bytecode form.
Any one has any idea of list of files to which the original scripts are passed to spidermonkey from the browser.

What do you mean by encrypted, ciphered or minimized? If it is a minimized
and obfuscated version, there is nothing you can do. Otherwise you might
try to instrument spidermonkey to dump each function raw either by looking
at the compressing thread or by calling toSource on all functions.

I haven't tried it in a while, but I believe that
<https://addons.mozilla.org/en-US/firefox/addon/javascript-deobfuscator/> does
something similar to what you describe here.
