+obfs4proxy is a tool that attempts to circumvent censorship by
+transforming the Tor traffic between the client and the bridge. This way
+censors, who usually monitor traffic between the client and the bridge,
+will see innocent-looking transformed traffic instead of the actual Tor
+traffic.
+
+obfs4proxy implements the obfsucation protocols obfs2, obfs3, and obfs4.
+
+It is written in Go and is compliant with the Tor pluggable transports
+specification, and its modular architecture allows it to support
+multiple pluggable transports.

+Subject: Bug 24793: Send the correct authorization HTTP header for basic auth.
+
+Apparently I didn't test the "connect via HTTP(s)" proxy with
+authentication at all when I added that functionality, so it has been
+broken for years.
+
+This should fix it now.
