I've developed an unfortunate eye condition where, in addition to the cataract in my right eye, I have extreme uveitis which results in me not being able to view anything bright without squinting heavily.
Sites such as RAWK which have a bright white background have therefore become almost unusable on PC, and pretty much the same on mobile now that Tapatalk no longer works.
Fortunately, I discovered an Extenstion for the Firefox browser that allows you to apply a 'dark' mode to any website - just sharing it here for anyone else who may be struggling with something similar.
It's called: "Dark Mode" (refer

Dark theme and night shift mode for every website. Care your eyes, use Dark Mode for night and daily web browsing.
