I so wanted to read the page but after 10 seconds of the high contrast white text on pure solid black background I started developing a headache.
You can also use extensions like that to set the contrast to a more comfortable level on websites that are already dark.
I highly recommend this if you have light sensitivity issues like me.
Also note that when the contrast on a page is higher, you can generally get away with lower brightness. This is pretty convenient on phones, and probably more necessary as well since on a phone you're more likely to have an OLED screen that really surfaces extreme contrast like white on black.
