Tor's website advises against mixing levels of anonymity, but does this apply across browsers? That is, can I browse websites in Firefox, chrome, IE etc without exposing my Tor traffic in Vidalia?
Edit: What I had originally meant with "mixing levels of anonymity" is actually "mixing modes of anonymity" (https://trac.torproject.org/projects/tor/wiki/doc/TorifyHOWTO#DonotmixModesofAnonymity , thanks mirimir). Now that I see that section again, I realize it is dealing with a separate concern. What I meant to ask was will it compromise my tor traffic if I simultaneously use a different browser to access easy identifying websites (i.e. account with my real name or email address connected to them). Nicolas and mirimir answered this to the effect of using VMs. Thanks!
