Firefox new debugger - Where did the file tab go?

Feel really stupid for asking but where did the file tabs in the debugger go? I can only open one file at a time. If I try to open another one, the file content is simply replaced with the new file. If I revert back to the old debugger, then I have a file tab for each file I open.

Using Firefox 53.0.3 (64-bit) on Ubunto 16.04LTS

You're actually using the old debugger UI. It's the new frontend that allows to open several files at the same time and looks like this:

Firefox DevTools new debugger frontend

To toggle the new debugger UI, go to about:config and set the preference devtools.debugger.new-debugger-frontend to true.

You may also check whether browser.tabs.remote.autostart.2 is set to true, which controls whether Firefox runs in multi-process mode.
