How to make a java script function restart?

Question

Mozilla Firefox

There is such a function that is launched when you click in the add-on, how to make it so that after clicking ana it starts, for example, every 3 seconds endlessly

activate: function() {
    ProxyAddonBar.reset();
    ProxyAddonBar.parseProxyList(function(ip_addr) {
      var rand_proxy = ProxyAddonBar.randomProxy(ip_addr);

      if(rand_proxy[3] == 'http') 
      {
        ProxyAddonBar.connectTo(rand_proxy);
      }
      else 
      {
        ProxyAddonBar.connectToSSL(rand_proxy);
      }

      document.getElementById('ip-address').children[0].value = ProxyAddonBar.getIPAddress();

      ProxyAddonBar.proxyList = ip_addr;

      ProxyAddonBar.addItemsToProxyList();
    });
setTimeout("function()",5000);},

Answer 1

Instead of setTimeout, use setInterval
But only remember the interval ID so that you can stop later when the function is executed or completed successfully.
Yes, and you have the wrong call.
Need something like this:

var iv1;
function  myInterrator() {
   myobject.activate();
}
iv1= setInterval(myInterrator, 3000);
