I tried starting it as firefox --safe-mode mode instead. The problem still exists, although it looks a little different, presumably because the Menu Bar isn't enabled. It starts up without any space between the title bar and the tabs. Right clicking above the tab gives the pop-up menu but with Menu Bar, Bookmarks Toolbar and Customize greyed out. Selecting Menu Bar produces some space where the Menu Bar would go, but no menu bar. The option in the right-click menu then has a tick beside it.

In the "Session and Startup" dialog, I've added Firefox as an "Application Autostart", using the simple command "firefox". This has previously worked fine, but since upgrading to Ubuntu 17.04, Firefox starts up with the Menu Bar missing (below the title bar). Non-active window tabs are also greyed out. It's 100% reproducible. If I shut down Firefox and restart it, it works fine.
