Yes, everyone knows you can change the user agent string, but how do you change the list of plugins returned by the browser? Do you have to actually patch the binary?!

You can set plugins.enumerable_names to the empty string, or to the plugins you want returned. Unfortunately, this was recently removed.[1]

navigator.__defineGetter__('plugins', function(){ return new Object(); });

Of course, you'd actually have to do a bit more work to make it bulletproof (otherwise fingerprinters could use the fact that you modified your default navigator object as a way to uniquely identify you !)

I imagine ultimately it's almost impossible to defeat fingerprinters in JS, as they could do tricky stuff like timing attacks to get you.

Use NoScript if you're concerned.
