1. edit /etc/default/grub, set grub_timeout to 0. Run update-grub so the change sticks.

This removes the ticking 5s timer at bootup. I never use the other boot entries anyway, and if the system fails to boot, I troubleshoot from a live system.

  1. Create ~/.config/gtk-3.0/settings.ini and add:
    [Settings]
    gtk-primary-button-warps-slider = false

This makes it so when you click on a scrollbar below or above the slider, it moves down or up by one page, not to where you clicked.

  1. edit /etc/environment (it’s empty), add a line with: MOZ_ENABLE_WAYLAND=1

This forces firefox to use Wayland, which makes scrolling much smoother and text look better.

There’s a bunch more, but these are the first I always do so I don’t get mad. What are yours?
