Do not reuse circuits for cross origin requests
|Target version:||Orfox RC|
The Tor Browser draft includes defenses against cross origin linkability
I have tested this with Facebook's mobile onion site (https://m.facebookcorewwwi.onion/)
In my tests, having a circuit built already will resolve on average 3 seconds faster in XHR requests. I tried 10 requests with a circuit built to facebook already and 10 requests without.
