I was a big flash junkie. When firebug came out, my first thought was “why isn’t there a swfbug”. It was amazing. You add a script and your page has a built in debugger. I made my php pages have a special url param __firebug=1 and it would load with firebug. Firebug had other nice things where you could respond with server traces. Made it really nice to debug server perf too. I remember how mind blown I was when I read the firebug source code. At that moment I wanted to a competent enough programmer to write that kind of code. Jquery was another huge eye opener too. I did write a react like dom differ back in the day but js was too slow.
