I spent a good amount of time working on Firebug before the decision to rewrite it as DevTools was made. After that, it was hard to justify time on a EOL project and I had just started as employee 7 at Weebly.

But I loved working on it. The team was great, and special kudos to Honza for staying with it through all the years. We had so many ideas, to help in debugging and to help in learning. Many yet to come, I'm sure. So much left to be done in all the developer tools on all the platforms.
