That sounds as good as any. "Spinner" didn't seem right, and is too ambiguous. Thanks @TyDraniu!

Note that you can create a new Number pref on the about:config page to change the moving loading indicator to an hourglass.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.


Firefox 63+ has support for "@media (prefers-reduced-motion)" and you can create a new Number pref named ui.prefersReducedMotion on the about:config page to enable or block some animations. In Firefox 78+ this includes the location bar breakout. In Firefox 80+ this replaces the tab loading indicator with an hourglass.
