The reason for this is described in the Firebug blog: https://blog.getfirebug.com/2016/06/07/unifying-firebug-firefox-devtools/
In short, Firebug 2 doesn't work anymore once multi-process Firefox <https://developer.mozilla.org/en-US/Firefox/Multiprocess_Firefox> is enabled. Therefore Firebug got integrated into the Firefox DevTools as a theme.
