Heisenberg Keypress

Breakpoint in JavaScript on keydown. When hit, focus shifts to debugger. The keypress never comes.

I can't observe both the keydown and the keypress event. If I observe the first one, I can't observe the second one.

Good to know. Bad to have to know.

Firefox Debugger GUI

It appear to be the case that...

...the breakpoint markers cover the green instruction pointer completely?!

Oh, and how hard would it be to add the keyboard shortcut to the step button tooltips?

[...let's try installing Firebug and see if that's better...]

Ok, Firebug installed. Conflicting Dashboard F12 binding disabled (Dashboard -- what is it good for?).

Oh, 'Debugger not activated'....how do you turn it on...

Oh, the other debugging session with the built-in debugger caused it to not work.

Ah, finally. And praise the firebug developers or whatever: the Firebug 'instruction pointer' is on top of the ...breakpointers.

...and, more goodness: the step buttons have shortcuts in their tooltips!
