console.log(() => { }) // <unavailable>  background.js:1
is bug 1393166, can viewed in Add-on Debugger.

The output of console.dir and console.log is different in the browser console (and partially also in the WebExtension Addon Debugging window) for two reasons:

- Bug 1327280 ([e10s] Browser console doesn't display objects from content processes (displays <unavailable>)), is the reason for the "<unavailble>" in the Browser Console when the extension is running in the extension process (currently only on Windows  the webextensions are going to run in the extension process by default)

- Bug 1362023 (Enable new console in browser console) and Bug 1347127 (Enable new console frontend in Browser Toolbox) are likely to be the reason for the different output of console.dir
