Very hard to link with your name or other elements of your "real identity" (unless you ever give them out over Tor).
Probably only slightly hard to link all the things you do using a given installation of the browser to each other. They do at least try, but it's still basically Firefox, and it's not clear that it's even possible to make an unfingerprintable browser.
