That you see *Inspect Element with Firebug* again means that the preference browser.tabs.remote.autostart.2 is set to false for you. See my related answer on Stack Overflow <https://stackoverflow.com/a/40748127/432681>. As far as I know, this doesn't happen by itself, so it might be that it happened with an update of Firefox or another add-on or you turned off multiprocess Firefox <https://developer.mozilla.org/de/Firefox/Multiprocess_Firefox> manually.
Please note that Firebug will definitely stop working once Firefox 57 is released, which will happen in November this year. With that version Firefox restricts its add-on support to WebExtensions <https://blog.mozilla.org/addons/2016/11/23/add-ons-in-2017/> - and Firebug is based on another (then incompatible) technology. So, you're definitely better off getting used to the Firefox DevTools <https://developer.mozilla.org/en-US/docs/Tools/> already. I've written a migration guide <https://developer.mozilla.org/en-US/docs/Tools/Migrating_from_Firebug> some time ago to make the live of Firebug users a little easier.
