Disable blind redirects
Redirecting to another page without giving any choice is hostile to users (you never know if that shortened url leads to hello.jpg) and can be a security risk. It should be disabled. Firefox has a pref to disable it: "Warn me when websites try to redirect or reload the page" which should be set in Tor Browser.
