no command line interpreter in Browser Console

According to this page https://developer.mozilla.org/en-US/docs/Tools/Browser_Console my browser console (Ctrl+Shift+j) should have command line interpreter but it doesn't. My browser is Firefox stable 69.0.3. Is this feature available only in Firefox Developer Edition?

Solution

  • I was just having this problem but found the solution. There is a little note on the mozilla website that says:

    NB: The Browser Console command line (to execute JavaScript expressions) is disabled by default. To enable it set the devtools.chrome.enabled preference to true in about:config, or set the "Enable browser chrome and add-on debugging toolboxes" (Firefox 40 and later) option in the developer tool settings.

    Ctrl+Shift+I - opens up the web developer tools.

    F1 - Opens up preferences

    Then right at the bottom there's a tick box that says "Enable browser chrome and add-on debugging toolboxes". This needs to be turned on.
