Open the debugger
=================
There are three ways to open the debugger:
- Select the *Debugger* panel in the Web Developer Tools, accessible from the Browser Tools submenu
- Press :kbd:`Ctrl` + :kbd:`Shift` + :kbd:`Z` on Windows and Linux, or :kbd:`Cmd` + :kbd:`Opt` + :kbd:`Z` on macOS (starting in Firefox 71; prior to Firefox 66, the letter in this shortcut was :kbd:`S`).
- Press the menu button |image1|, select "Developer", then "Debugger".
