I'd like to know how safe is it to use the Tor-browser-bundle (for linux, in case it matters) at the same time as another browser (firefox, in case it matters) normally installed, and why. Now I am closing it, but often I would rather not close it. I haven't found but one and unclear answer to this.
More generally I would like to know if other internet traffic: amule, email clients, social software (pidgin) etc. that are not configured to use Tor (I understand they shouldn't) should be stopped when using the Tor browser bundle.
