Firebug stopped working


Well-known member
Not sure which the correct forum is for this but hoping someone can help.

I'm on macOS Sierra with Firefox 51.0.1

I have firebug installed (and have done for years). When I go to use it now though, it just opens up the Firefox dev tool (which is no where near as good).

Both Inspect Element and Inspect Element with Firebug give the same interface now. The Firebug one used to be far moreuseful.

To be honest the new one isn't that much different and for the most part the only things I miss about firefox/firebug were some of the quirks it had which exposed certain things not exposed in the other dev tools.

Unless I actually need those quirks to debug something (which is getting rarer and rarer) the built in dev tools work just fine, just a matter of getting used to the visual and layout changes of the app IMO.

Firebug is no longer needed. Browser developer tools have surpassed it. It might take time to get used to different interface.
