Firebug. The tool that has been long replaced by Firefox’ native developer tools but nevertheless has wide-spread acceptance among developers. With Firefox’ switch to e10s (multi-process Firefox), however, the extension will no longer work, and its authors now announced that they won’t port it over as a new extension either. Instead, they will focus on providing a Firebug theme for native dev tools and improve those.
