I am using firefox developer edition. I have it configured with several programs that give it a dark theme. My biggest problem with it is that because my eyes adjust to the screen being dark, the flash of unstyled content hurts my eyes whenever I open a web page.
I am wondering if there is any sort of configuration I can do to fix the fouc. I am perfectly willing to go as far as modifying the base colors in the source code if I need to. I have not been able to find anything useful on the internet. Is there anything I am able to do about this? Maybe change the color values in the source code?
