I want more color adjustment features

[wutongtaiwan]

While it's possible to install themes in Firefox, these themes only affect the color at the top of the browser, and most of the middle area follows the system, which is either white or black. As I screenshot shown

I want to have the same color customization features as Chrome, and even the color of the logo can be changed. In terms of the aesthetics of the UI, you still need to work harder
