Colours are exceptional and excellent..

Dark mood

I wish it synced between different devices through my Mozilla account. I haven't found a way to access my saved themes other than pressing the "random" button & saving the result to get to the menu. (Though that may just be user error). Overall very nice, allows me to customize my browser in a way that I found usable & pleasing to look at.

unable to add transparency to almost all items. this limits your custom imagery to a very limited area, minimizing the entire point of the exercize.

Functionally unusable if you just want to tweak the colors of the standard theme. If I change the color if a single thing, it changes the colors of everything to the stupid theme the add-on starts off with.
