Firebug was a must-have tool for many front-end developers, as well as developers who chose to use Firefox for Firebug.

In fact, the Firebug stop has long been a harbinger. At the end of 2015, Mazilla engineers were working on the integration of native Firefox developer Tools (DevTools) and Firebug in order to further provide more powerful functionality.

In terms of results, Firebug 3 is no longer a separate tool, but a shell above the devtools. It provides Devtools with the same topics as previous versions of Firebug. Users can open a theme by clicking the firebug theme option. Firebug stop, the equivalent of removing the devtools layer of shell.
