Hi, @armandocat, after some DMs with @reggaemuffin on Discord, he said for me to comment here. I installed the add-on onto Firefox. However, the Votes was not working. I just had a circle going around. The four grids on the top right did nothing. So I disabled the add-on.

Well, Voila! Now the add-on works in the disabled position. The Votes and posting bar graft works. The four grids are now two and they allow me to switch styles. I realize that you have lots of free time, so now here is another mystery of the universe to ponder.
