Same. I remember what an epiphany Firebug was, and I felt bittersweet later when quality dev tools started being built-in, just because it seemed a little sad to think Firebug wasn’t going to be needed anymore.
Same for me. There was also a time when Chrome dev tools builtin was superiour to the Firefox builtins or Firebug, respectively.
Nowadays, I don't know what to think about built-in dev tools. On the one hand, they promise lowering the entry barrier for fellow ongoing devs. On the other hand, they apparently aren't, because many folks don't care about learning all the basics of HTML, JS, CSS, etc. any more but instead prefer to enter the development world on a framework level. Developer extensions like "Vue tools" make stuff only more complicated, not less, thought.
