Inspecting firefox with firebug

Using ColorZilla I found an interesting feature. If I pick a color from firefox (bars,tabs or anything else of the browser) and then go to:

ColorZilla > Inspect Last Element > In Firebug

Then I can see the markup,css,js that firefox uses in the firebug panel just like a website.

Is there any solution to view th开发者_运维技巧is code without use Colorzilla?

As mentioned in the comments, Chromebug is no longer working with current Firefox versions. Instead of opening the limited chrome://browser/content/browser.xul page, you can make the browser chrome accessible to the scratchpad. Open the about:config page and set devtools.chrome.enabled to true, as described in the extension development environment setup guide on MDN.

Open the JavaScript scratchpad (Shift+F4) and select the browser context environment. Now you can type in something like window or document.getElementById('urlbar') and click the inspect button or hit Ctrl+i. This will evaluate the expression and open the element inspector, which shows all properties of the element.

It sounds like you're after Chromebug.

Chromebug is the Firebug code adapted for XUL applications. It is the debugger that Firebug developers use to develop Firebug.

So you can debug your debugger, you know?

There is actually a dedicated version of Firebug for that called Chromebug (Named after the chrome of Firefox, not Google's chrome)
