Even though there are many creative ways to set a preference on the Browser Toolbox profile, it will be easier to have a checkbox option in the options panel that toggles devtools.browsertoolbox.fission.

This option should only be available in the Browser Toolbox.

Even though there are many creative ways to set a preference on the Browser Toolbox profile

While I remember, here are some of the tricks shared by DevTools peers to set preferences on the Browser Toolbox profile:

  • (macos only): right click on the icon of the Browser Toolbox in the dock, select "New Window" and navigate to about:config in this new window
  • create a script updating the preference, and set it as the MOZ_TOOLBOX_TEST_SCRIPT environment variable
  • open Scratchpad in the browser toolbox, click on the deprecation link. It will open a new window, from there go to about:config
  • open your profile folder, go to chrome_debugger_profile, update prefs.js
  • open the Browser Toolbox's Toolbox, and either call Services.prefs from there, or use etc...
