"The story of Firefox and Firebug is synonymous with the rise of the web. We fought the good fight and changed how developers inspect HTML and debug JS in the browser. Firebug ushered in the Web 2.0 era. "
I love, used and appreciate firebug as much as the next guy but this is a bit much. Its a great product that helped alot of people it's not an ideal to fight for nor "ushered" in web 2.0.
I was building web products professionally before and after Firebug and the difference was staggering. It opened up the full possibilities of CSS and JavaScript like no other tool before it.
Having been a developer since Web "1.0" it's not exactly wrong, but I think you're interpreting that incorrectly.
Without Firebug a lot of the JS development that was basically required for Web 2.0 sites would have been much much slower and even more complex to maintain.
It didn't create Web 2.0 (arguably that had been a thing since 2003-2004, and the term dates to ~99) but it did usher it into mainstream development due to making it less painful to create that content.
Do you not remember what it was like in the years (nearly decades) prior to firebug? alert() still gives me nightmares. Firebug was easily as huge as AJAX, ES6, and other such milestones.
