Style Side Panel
Inside the Style side panel you can see the CSS styles, that are currently assigned to the selected node inside the HTML Panel. It also offers you similar possibilities of CSS manipulation like the CSS Panel. The difference between them is organizational. The Style side panel is a live view of the styles assigned to the selected node inside the HTML Panel (which can be in different CSS files) while the CSS panel shows all styles of a CSS containing file.
This menu is reachable via the little arrow in the panel tab ( ) or by right-clicking on on the panel tab (since Firebug 1.9).
