Mozrepl:当进入一个新打开的窗口时，转到浏览器窗口的上下文

Question

我的问题是，我不能上升到浏览器窗口上下文后创建和使用mozrepl进入一个新的窗口，如何做到这一点?

ubugnu@spin-foam:~$ telnet localhost 4242 | tee -a .repl_log
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Welcome to MozRepl.
 - If you get stuck at the "...>" prompt, enter a semicolon (;) at the beginning of the line to force evaluation.
 - If you get errors after every character you type, see http://github.com/bard/mozrepl/wikis/troubleshooting (short version: stop using Microsoft telnet, use netcat or putty instead)

我对mozrepl一点也不熟悉。但是从我在你的代码中看到的，也许你可以尝试win.opener来访问你所在的当前窗口的打开器。如:

repl.enter(win.opener);

或者你可以尝试访问类型为"navigator:browser"的最新窗口，如果你可以访问组件(Cc,Ci,Cu):

var window=Cc["@mozilla.org/appshell/window-mediator;1"].getService(Ci.nsIWindowMediator).getMostRecentWindow("navigator:browser");
