Answer 1

被选择一个新的标签，每次记录当前的URL到错误控制台一个完整的例子：

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);
