Test results of effectiveness of browser privacy extensions

1. How does HTTP Switchboard compares to AdBlock , Ghostery or Disconnect concerning privacy? (link posted by someone in another thread on Wilders somewhere)

2. Ghostery-sponsored test results of 1,000 popular websites: http://www.areweprivateyet.com/

Firefox users: you can conduct your own tests with Network Monitor. You probably should clear the browser cache entirely before testing a given site; this extension allows you to clear the cache more quickly.

Non-Firefox users: I think Fiddler can be used to conduct your own tests. You probably should clear the browser cache entirely before testing a given site.

I'm not sure if anyone here at Wilders is allowed to post their own test results, due to the Wilders test policy (not sure if it applies to just malware tests).
