// Switch proxies after X seconds
// Rotate through a list of proxies, switching every _secondsToSwitchAfter_,
// one for each URL (not for each website -- but for each URL that is loaded)

// Define proxy list first
var proxies = ["PROXY myproxy.foo.com:9050", "PROXY myproxy.bar.com:8080",

// Round robin
// Rotate through a list of proxies, in order, one for each URL (not for each website -- but for each URL that is loaded)

// Define proxy list first

=================

// Random
// Randomly rotate through a list of proxies, one for each URL (not for each website -- but for each URL that is loaded)

// Define proxy list first
var proxies = ["PROXY myproxy.foo.com:9050", "PROXY myproxy.bar.com:8080", "PROXY myproxy.baz.com:6667"];
