Anyone who has read my recent HN posts would know that I proudly disable JavaScript in my browsers and have done so for several decades.<p>Now <i>Privacy Analyzer</i> has given me yet another excellent reason to continue doing so. Without JavaScript running <i>Privacy Analyzer</i> WON'T EVEN START let alone give you any useful information! These tests were done on both a PC and on an android smartphone with security plug-ins/add-ons disabled and the results (given the differences in technology) were essentially the same. Note: several browsers had no plug-ins installed, only JS disabled.<p>As I've been saying for years, the first line in defence of your privacy is to turn JavaScript off, all other protection measures, whilst useful, are of secondary importance.<p>Moreover, <i>Privacy Analyzer</i> is essentially useless even with JavaScript turned on. With just one add-on <i>(Secret Agent)</i> running, it successfully spoofed my location (randomly put me on the other side of the world), put me on another—now incorrect—IP address, randomly changed my User Agent to nothing like the one I was using, and <i>Privacy Analyzer</i> didn't know my PC's processor (among other things that it had also gotten incorrect).<p>I know I sound like a repeating scratched record about JavaScript—but don't take my word for it, just do the tests and prove what I'm saying for yourselves.<p><i>BTW, if you want to do these security/privacy tests both with and without JavaScript enabled then I'd suggest you use Steve Gibson's 'ShieldsUP!' — GRC (Gibson Research Corporation) <a href="https://www.grc.com/shieldsup" rel="nofollow">https://www.grc.com/shieldsup</a>. It's been around for years and works well.</i>
