How do you run one line of JavaScript at a time in Firebug?

Question

So I just started using Firebug to debug JavaScript, and I have no trouble setting breakpoints, but how can I run one line at a time after hitting a breakpoint? Is there any way to do this without manually setting a new breakpoint each line?

Answer 1

Have a look at the upper right corner:

The button Step over which I annotated with Move to next line, executes the current line and goes to the next one. Step by step. To also execute called functions step by step, you have to click on Step into (annotated with Go into function call).

Answer 2

Just press F11 to single step. Or press the "Step into" button.
