How to add css selector in firebug' style's area?

Question

How to add new css class or id and then write properties for html element in firebug's right side css pane. like we can write in web developer toolbar > edit css

Answer 1

You can right click on Style Tab then Edit Element Style... or New Property...

You can also enable/disable styles by clicking a RED Circle with diagonal line. If the style becomes grayed it means that it is disabled.

Answer 2

Dunno if I'm too late with this, but if you go to the CSS tab in Firebug, then Edit one of the CSS scripts, you can add the class selector and CSS anywhere, and your changes will show up immediately.

Answer 3

Actually none of the answers were correct... Edit element style edits the inline style of the element. New propery adds a new css property to the actual css selector, what you clicked on. There is an Add rule menu, when you right click on the css part and there you can define a new selector and this was the original question.
