firefox某些网页账号和密码的记录问题？

用firefox在登陆起点中文网、新浪邮箱等网站时，它并没有跳出记录账号和密码的选项，请问如何能让这些受加密的网站也能被记录账号和密码，因为这些网页登陆次数比较多，也不是很重要，所以可以忽略安全性的考虑。

没人知道吗？高手帮忙解答一下！

试试以下代码

javascript:(function(){var%20ca,cea,cs,df,dfe,i,j,x,y;function%20n(i,what){return%20i+"%20"+what+((i==1)?"":"s")}ca=cea=cs=0;df=document.forms;for(i=0;i<df.length;++i){x=df[i];dfe=x.elements;if(x.onsubmit){x.onsubmit="";++cs;}if(x.attributes["autocomplete"]){x.attributes["autocomplete"].value="on";++ca;}for(j=0;j<dfe.length;++j){y=dfe[j];if(y.attributes["autocomplete"]){y.attributes["autocomplete"].value="on";++cea;}}}alert("Removed%20autocomplete=off%20from%20"+n(ca,"form")+"%20and%20from%20"+n(cea,"form%20element")+",%20and%20removed%20onsubmit%20from%20"+n(cs,"form")+".%20After%20you%20type%20your%20password%20and%20submit%20the%20form,%20the%20browser%20will%20offer%20to%20remember%20your%20password.")})();

把代码保存为书签,然后在需要的网站上访问此书签就可以了.

在起点中文网，使用以上代码的书签后，显示如下：

Removed autocomplete=off from 0 forms and from 0 form elements, and removed onsubmit from 0 forms. After you type your password and submit the form, the browser will offer to remember your password.

仍然不能记录账号和密码！

没去过起点,不过听说opera也不能在起点记录密码,估计是起点自己的问题.
新浪我测试过 用那段代码后是可以记住密码的.

谢谢了
