+           
+	This ruleset covers DuckDuckGo Onion service on Tor.
+	Note: This should be something like platform=tor, to indicate
+	that these rules should not go through the fetch tester on the
+	non-Tor Internet because they will fail. As an approximation to
+	that, we just use platform="mixedcontent", since Tor Browser is a
+	mixedcontent platform, and the https-everywhere-checker will skip
+	non-default platforms.
