1. By default, on some Macs, the function key is remapped to use a special feature: for example, to change the screen brightness or the volume. See this guide to using these keys as standard function keys. To use a remapped key as a standard function key, hold the Function key down as well (so to open the Profiler, use Shift + Function + F5).

Note: Before Firefox 66, the combination Ctrl + Shift + S on Windows and Linux or Cmd + Opt + S on macOS would open/close the Debugger. From Firefox 66 and later, this is no longer the case.
