回答1:

Firebug is officially discontinued. New installations of Firefox have multi-process enabled. With that the Firefox DevTools are opened instead of Firebug when you click the Firebug button and a notification is shown giving a short explanation:

You can get Firebug back by deactivating the multi-process feature, though this is only a short-term solution, as multi-process will be mandatory at some point.

Firebug is (sadly) no longer updated, or supporting latest Firefox versions.

If you like Firebug and Firefox, then you can use:

• Waterfox 55 (based in FF56)+ Firebug 2.0.19 (install extension and restart)
• Palemoon 27.6 (based in FF pre Australis and FF52 upgrades) +firebug 1.12.8.1
• An oudated and non supported Firefox

Waterfox and Palemoon are active projects, and they will continue supporting classic Firefox extensions/addons
