Just to follow up on my earlier comment: so the new Firebug crapped out the very first time I tried to use it. I've already reverted to 1.4.<p>I don't understand this project. Serious web app developers are, I guess, not their target audience.<p>Edit: it's not like 1.4 works either. I set breakpoints and they just get ignored. Grrrrr.<p>Edit 2: so I resort to putting "debugger" keywords in my JS and Firebug breaks into the debugger at an entirely different source location. Grrrrr ^ 2.
