Firebug - how to reduce indentation of nodes?

Is there any way to access the stylesheets that make up firebug to edit things like the indent distance for nested DOM nodes? Looking for a location of some .css files or somethi开发者_开发知识库ng that I can override.

I frequently find myself working with deeply-nested nodes that are pressed up against the right side of firebug, while the whole left side is unusable whitespace.

In Stylish Firefox extension, you can use this code to remove the indentation in the dom panel. I have to look further to see how to decrease the indentation on child nodes (it's a good userstyle project, btw) :

.memberLabelCell{
padding-left:0 !important;
}

Edit: Here is a little userstyle which reduces the indentation of nodes in html and dom panels : http://userstyles.org/styles/42885 (you need stylish to use it)
