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 IceCat 71; prior to IceCat 66, the letter in this shortcut was :kbd:`S`).

- Press the menu button |image1|, select "Developer", then "Debugger".
