How do I POST to a web page using Firebug?

Answer 1

NO NEED of plugins !!

Just drag any url in BOOKMARK BAR, then right click and EDIT, and insert javascript code:

javascript:var my_params=prompt("Enter your parameters","var1=aaaa&var2=bbbbb"); var Target_LINK=prompt("Enter destination", location.href); function post(path, params) {   var form = document.createElement("form");   form.setAttribute("method", "post");   form.setAttribute("action", path);   for(var key in params) {  if(params.hasOwnProperty(key)) {        var hiddenField = document.createElement("input");      hiddenField.setAttribute("name", key);      hiddenField.setAttribute("value", params[key]);         form.appendChild(hiddenField);  }   }   document.body.appendChild(form);  form.submit(); }   parsed_params={}; my_params.substr(1).split("&").forEach(function(item) {var s = item.split("="), k=s[0], v=s[1]; parsed_params[k] = v;}); post(Target_LINK, parsed_params); void(0); 

then enter the target site-link, and click that button in BOOKMARK BAR! That's all!
