Would give 5 Stars if we had the ability to also change the newtab/Firefox Home page. It is really annoying having everything in a dark colour scheme and then having this really out-of-place-looking white page every time you open a new tab.
UPDATE: This is now supported so here are your 5 stars

thanks a lot !! <3

Really needs to be able to create a dark mode on the new tab page. That thing is blinding after using dark mode everywhere else. It feels like something so simple. Either have it match the system theme on macOS, or a simple light/dark toggle. Doesn't have to be customizable or theme matching (yet), just has to not blind me. Otherwise, really cool being able to tweak your theme, would be 5 stars without this surprisingly uncomfortable experience.

needs a darkmode option for new tabs, and the ability to upload and crop high res images for tabs, background, and new tab page.

酷！配色多！自定义能力强！
