  Simplify running browser tests through a proxy server
  by adding your frequently-used proxies here.
  
  Now you can do something like this on the command line:
  "pytest SOME_TEST.py --proxy=proxy1"
  
  Format of PROXY_LIST server entries:
  * "ip_address:port"  OR  "username:password@ip_address:port"
  * "server:port"  OR  "username:password@server:port"

  Example proxies in PROXY_LIST below are not guaranteed to be active or secure.
  If you don't already have a proxy server to connect to,
