Some years ago I stopped using Firebug. I made a brief jump to Chrome but somehow I felt more at home in Firefox, and now I no longer needed FB to do my job.

Pretty much every single workday I have entered something or other into the console. I hop around Alt-Apple-K/Apple-Shift-I/etc. I inspect my elements. I loved it when recently an event listener list popped into the DOM view. I have followed your checkboxes and your changes and it has by and large been very much for the good.

Free software makes me feel good. Mozilla Firefox is one of my favorite pieces of software and I develop against it and use it and make a living with it. Kudos.
