A part of me is annoyed that Firefox has spent so long trying to build a set of dev tools when Firebug was already an established tool for them.
I agree that the dev tools are a lot better, and I've recently removed Firebug as well, but I've spent many months annoyed at Firefox dev tools appearing when I've wanted to inspect an element using Firebug. Firebug has been a resource hog for a long time now, but I feel that I stuck with it for longer than I should have because the Firefox dev tools were an annoyance.
Is there a specific reason why Mozilla didn't just ask the creator of Firebug if they could merge his work into the Firefox source, and build on the creators already good work.
We thought long and hard about including Firebug wholesale and considered several approaches to integrating it. An early prototype of the Inspector even included a significant portion of Firebug. Ultimately, integration proved to be too challenging and would have required rewrites that would have been equivalent to starting over.
