Not just `about:config`, which is limited to non-release builds, but via enabling “Secret Settings” when you enable debug mode: https://firefox-source-docs.mozilla.org/mobile/android/fenix/Secret-settings-debug-menu-instructions.html https://firefox-source-docs.mozilla.org/mobile/android/fenix...

I think Nimbus experiments also might have exposed the setting.
