If you are asking whether the act of browsing SR left a trace on the computer, no. TorBrowser does a good job of state isolation. It caches nothing to disk, flushes browsing history, cookies and various other things on shutdown, uses separate plugins, so even if you used Flash, that would no mix state with a system installed version. The only way it leaks browsing activity is through positive actions taken by the user, such saving bookmarks. (It even goes so far as to disable some positive actions, like saving passwords) The biggest thing in your case is the bookmark to SR.
