Use Firebug in Any Browser

Just include this script on the site and you'll get a Firebug console that pops up for debugging in any browser. Not quite as full featured but it's still pretty helpful! Remember to remove it when you are done.

<script type='text/javascript' src=''></script>


Firebug Lite (drag that link to bookmarks bar)

Bookmarklet Code

javascript:var firebug=document.createElement('script');firebug.setAttribute('src','');document.body.appendChild(firebug);(function(){if(window.firebug.version){firebug.init();}else{setTimeout(arguments.callee);}})();void(firebug);

    Save the file linked in the upper code to the UserJS directory as a JS code with .js extension and you will be able to use it in every page you visit ( In Opera this worked, it should in others too. Yes, I know, Opera has its own developer tool. ).

    It’s very bad comparing to original Firebug.

    It’s all good except as with all editors it won’t hold, I take out and
    replace Meta content, the one there is full of rubbish..
    refresh and it reverts back.. I have searched the net for 3 years
    looking for something on line and I sort of hoped this was it.
    Is there some little thing like here
    is it that simple, well what ever it is, it’s eluded me… and I’m
    slowly loosing the will to try anymore…
    all my blogs have $0.00 attached because I can’t change
    the Metadata, Please can you put me out of my misery.
    yours terry morris

    You guys should use this URL in your header to get the most recent (and stable) version of the script:

    Oh, also, in order to activate it in newer browsers like IE9 and Safari, you need to click F12.

    click f12?
    how do I click a keyboard key?
    are you serious?

      I think he meant “flick” not click, because snapping the F12 with thumb and index is possibly intended for more experienced users, but “flicking” the F12 key is something that just about anyone can manage.

    I have got few errors after including the script in my page :

    “Unable to get property ‘src’ of undefined or null reference (firebug-lite-compressed.js,68)”

    “Unable to get property ‘responseText’ of undefined or null reference (firebug-lite-compressed.js,71)”
