Proxy Manager 作者: Warren Bank

Features

Allows the user to:

• Configure the methodology to dynamically obtain a fresh list of proxy servers.
  • intended only for advanced users
  • the default methodology works nicely
• Enable the use of a proxy for all tabs, or for individual tabs.
• Refresh the list of proxy servers.
• Switch the proxy in use to another in the list.

Security

The default list of proxy servers is obtained from a publicly available list.

This has 2 important implications:

1. reliability
   • they don't always work
   • find a working proxy by:
     • allowing fallback to other proxies in list
       • which is default behavior
     • enable the proxy in a new tab
     • open the URL for a site that prints the IP of the HTTP client making the request
       • example: httpbin.org/ip
       • the IP it returns is the IP of a working proxy
     • select the working proxy in the list as the first proxy to use
2. security
   • don't pass any private information through these proxies without using an encrypted connection
   • don't ignore browser warnings for invalid HTTPS certificates
     • the proxy could be attempting to man-in-the-middle using a self-signed certificate
