-Troubleshooting
----------------
-
-* I can only load some websites  
-   Check the logs of local.py. If you see only IPs, not hostnames, your may got DNS poisoned, but your browser hasn't 
-    been configured to let the proxy resolve DNS.  
-   To set proper DNS config, you can simply install FoxyProxy / Autoproxy for Firefox, or ProxySwitchy / SwitchySharp for 
-   Chrome. They will set the config in your browser automatically.  
-   Or you can change network.proxy.socks_remote_dns into true in about:config page if you use Firefox.
-* I can't load any websites and the log prints mode != 1  
-    Make sure proxy protocol is set to Socks5, not Socks4 or HTTP.
-* I use IE and I can't get my proxy to work    
-    Since you can't specify Socks4 or Socks5 in IE settings, you may want to use a PAC(Proxy auto-config) script, or 
-    just use Firefox instead.
