Firebug 是火狐的一个插件，如果你想在IE、Opera和Safari上也使用Firebug调试网页，解决办法就是Firebug Lite。Firebug Lite是一个用JavaScript写的工具，直接在你的页面中导入Firebug Lite就可以使用Firebug插件的功能，而且支持IE、Opera和Safari。

原文：

Firebug is an extension for Firefox, but what happens when you need to test your pages in Internet Explorer, Opera, and Safari?

The solution is Firebug Lite, a JavaScript file you can insert into your pages to simulate some Firebug features in browsers that are not named “Firefox”.

Firebug Lite creates the variable “firebug” and doesn’t affect or interfere with HTML elements that aren’t created by itself.

Screenshots:

• IE
• Opera
• Safari

Latest Version: 1.2.1 (2008-09 CHANGELOG)

Installing Firebug Lite 1.2

Insert this line of code into any page that you want to contain Firebug lite:

    <script type='text/javascript'
        src='http://getfirebug.com/releases/lite/1.2/firebug-lite-compressed.js'></script>

Firebug Lite as bookmarklet

Drag the following link to your bookmark toolbar and use Firebug Lite on any page:

Firebug Lite

Configuring Firebug Lite

Height of the firebug lite form is resizeable in latest version;

  <script type="text/javascript">
  firebug.env.height = 500;
  </script>

Also, developers can use their own css file;

  <script type="text/javascript">

  firebug.env.css = "/myown/firebug.css"
  </script>

Using Firebug Lite Offline

Download the source

Import firebug-lite-compressed.js or firebug-lite.js into your site’s directory. Find “firebug-lite.css” URL on the javascript file which you imported and replace this with offline address of firebug-lite.css file.

    <script language="javascript" type="text/javascript"
        src="/path/to/firebug/firebug-lite.js"></script>

Commands

Now FBLite supports all basic commands of Firebug.

firebug.watchXHR: Use this function to watch the status of XmlHttpRequest objects.

    var req = new XmlHttpRequest;
    firebug.watchXHR(req);

firebug.inspect: Now elements can be inspected in javascript code:

 firebug.inspect(document.body.firstChild);

On some browsers, the console object is already declared. If you observe errors in Safari, for instance, use the console commands in this fashion:

    firebug.d.console.cmd.log("test");
    firebug.d.console.cmd.dir([ "test" ]);

Notes

On some browsers, the console object is already declared. If you observe errors in Safari, for instance, use the console commands in this fashion:

    firebug.d.console.cmd.log("test");
    firebug.d.console.cmd.dir([ "test" ]);

Firebug Lite creates the variables “firebug” and doesn’t affect or interfere HTML elements that aren’t create by itself.
