Answer 1

每次选择新选项卡时,将当前URL记录到错误控制台的完整示例:

function LOG(msg) {  
  var consoleService = Components.classes["@mozilla.org/consoleservice;1"]  
        .getService(Components.interfaces.nsIConsoleService);  
  consoleService.logStringMessage(msg);  
}  

function onTabChange() {
    var href = gBrowser.contentDocument.location.href;
    LOG(href);
}

window.addEventListener("load", function(e) {
    gBrowser.tabContainer.addEventListener("TabSelect", onTabChange, false);
}, false);

window.addEventListener("unload", function(e) {
    gBrowser.tabContainer.removeEventListener("TabSelect", onTabChange, false);
}, false);
