Process: -Create a new tab, dark theme works fine so far. -Go to any website, interface flashes white before site loads -site loads, dark theme returns

I have edited the chrome files. I have installed ShadowFox. I have read everything I can find about this issue and nothing so far has worked. Please save my retinas.
