Fyi: the loading page balls can be removed (am not sure how myself) https://www.howtogeek.com/333110/how-to-customize-firefox-quantum-and-remove-the-white-space-around-the-title-bar/ and https://www.howtogeek.com/333805/how-to-change-or-customize-firefoxs-new-tab-page/ and https://www.userchrome.org/

Note: Any customization will revert back to default, you will also need to reinstall Extensions.

Please let us know if this solved your issue or if need further assistance.

Hi StephenKnudsen, could you explain this problem further:

In prior versions I could use the "back" virtual button to go back multiple pages .... now I apparently cannot do this.

There still is a Back button, and if you right-click it there is a menu of the history of that tab. Is it not working, or not working the way it did before?

So many things I dislike about the New Firefox, especially that left-right "bouncing ball" when FF is loading something.

Those dots can be changed using a custom style rule, as can many aspects of the appearance of Firefox's interface. If you're interested in diving into that, it involves creating a userChrome.css file, and takes 5-10 minutes. Once you have the first rule set up, it's faster for the next one, etc.

This page describes how to create the file:

This discussion thread on Reddit has a rule that switches the dots back to the old circling arrow design:
