Today, Mozilla announced it was retiring FireBug. Inevitably native browser development tools eclipsed FireBug, but I can't help but say "Goodbye" as there are so very few singular pieces of software that have such a bearing on my life. When a friend of mine introduced me to FireBug, and I realized back in 2007 I could see in real-time the effects of CSS, little did I know it'd lead me down the path of web development.
