如果要兼容多浏览器就要判断用户的浏览器类型，如果是firefox还是ie6,7,8等，这样可以根据他们不能的区别进行判断再作操作。

简单代码
//添加到收藏夹
function addtofavorite()
{
if (document.all){
window.external.addfavorite(document.url,document.title);
}else if (window.sidebar){
window.sidebar.addpanel(document.title, document.url, "");
}
}
//设为首页
function sethomepage(){
if (document.all){
document.body.style.behavior='url(#default#homepage)';
document.body.sethomepage(document.url);
}else if (window.sidebar){
if(window.netscape){
try{
netscape.security.privilegemanager.enableprivilege("universalxpconnect");
}catch (e){
alert( "该操作被浏览器拒绝，如果想启用该功能，请在地址栏内输入 about:config,然后将项 signed.applets.codebase_principal_support 值该为true" );
}
}
var prefs = components.classes['@mozilla.org/preferences-service;1'].getservice(components. interfaces.nsiprefbranch);
prefs.setcharpref('browser.startup.homepage',document.url);
}
}
调用方法
<a href="#" onclick="sethomepage();">设为首页</a>
<a href="javascript:addtofavorite();" >添加收藏</a>
