Firebug is no longer compatible with Firefox.

More specifically, Firebug is not compatible with multiprocess firefox. If you need it, you can use Firefox ESR, which has multiprocess disabled by default, and maintains Firebug functionality.

NB: Firefox developer tools is not an acceptable substitute. Far too often, it will refuse to show anything in the CSS of a webpage -- it insists that there are no CSS rules in effect at all.

Note that with Firefox 57 (and 59 ESR) Firebug (as well as most other current extensions) will definitely stop working, as at that point Firefox will only support WebExtensions. Though that also means that Firefox will (actually already does) support extensions which were initially written for other browsers.

NB: Firefox developer tools is not an acceptable substitute. Far too often, it will refuse to show anything in the CSS of a webpage -- it insists that there are no CSS rules in effect at all.

This sounds like a bug, which I didn't experience so far. If you can break this down to a simple test case, you should file a bug report for that. Please CC me when you do so, so I can follow it.

Simple test case? So far, it's random -- about 70% of the time. Yes, it's very common for me, but it also goes away with a restart, and shows up from an unknown trigger.

Never experienced anything like that. Could it have to do with another
extension? Did you try in a fresh FF profile?

Did not consider other extensions. Did not try a fresh profile.

As far as I know, only Firebug prevents starting up in multi-process mode, so I figured none of the others would cause problems.

Did not consider other extensions. Did not try a fresh profile.

Instread of a new profile, you may start your normal profile in safe mode, which deactivates the add-ons temporarily. To do so go to about:support, click the Restart with Add-ons Disabled... and follow the instructions.

As far as I know, only Firebug prevents starting up in multi-process mode, so I figured none of the others would cause problems.

There are other extensions not working in multi-process mode, but this issue may be unrelated to that mode.

While we've discussed this issue here now, I want to note that we've hijacked Jorge's thread about why Firebug doesn't work in Firefox 55. Furthermore, this issue should better be discussed in the channels of the Firefox DevTools team, so they can provide help.
