Firebug Lite allows you to use Firebug in almost any browser! You can try it yourself in Internet Explorer, Opera, Safari, Chrome or any other browser that supports JavaScript. Firebug Lite is written in JavaScript, so all you need to do is add the following code block to the page:
<script type= 'text/javascript' src= 'http://getfirebug.com/releases/lite/1.2/firebug-lite-compressed.js' ></script>
* This source code was highlighted with Source Code Highlighter .
Or, even better, use this tab:
Firebug lite
')
Firebug Lite allows you to conduct a detailed inspection of DOM elements as well as it does in a regular Firebug. You can click the
Inspect button and specify the page element whose DOM properties or styles you want to learn.

It seems that this functionality has several problems, but there is another way to find out the properties of page elements - this is navigation through the element tree. Click on the "+" in the element tree and select the object you need. On the right you will see the styles and DOM properties of the selected object.
Firebug Lite also has a JavaScript console built in, allowing you to execute JavaScript code on the fly. You can write one line of code at a time or switch to advanced mode, where you can already write multi-line scripts before executing them.

Although it is not allowed to change the CSS properties for the selected element, Firebug Lite has a built-in mechanism to do this. You can call it “CSS console”, because here you can write your own CSS style and see what comes out of it.

Of course, this is not a full-fledged Firebug, if only because the name contains the word Lite. Also unfortunately, Javascript cannot be debugged in it (I can’t imagine how difficult it is to write a Javascript debugger in Javascript). So, you are still attached to your debugger, which you are using in your chosen browser. But at least Firebug Lite provides a convenient way to view the javasript code of files that are loaded on the page.
Firebug Lite also needs a Firebug feature such as viewing the padding, border and margin of the selected element in a convenient graphical form.
Anyway, it's better to have Firebug trimmed than not to have it at all. If you are trying to debug your markup in different browsers, this is a definite interesting tool that is worth a try.
Did you code something used firebug lite? Have you used Firebug in IE, Safari, Chrome or Opera before? If so, what are your favorite chips?
PS From myself I will add that this is a very, very limited version, but for a quick check it can and should be used (if there is nothing valuable at hand).
PS 2 - Huge request, sign off when you minus to at least know for what?
