piggybacking on this, the performance of Firefox on a Mac with a 4k external screen is abysmal. any action at all takes an extra second or two to perform. not to mention that if i start watching a youtube video it makes the fans go crazy.
i changed back to chrome because of this and it's so much smoother.
i have exactly the same issue. so many websites nowadays choose to have dark themes which are essentially black backgrounds with white text and it is physically painful to read. if i'm invested enough in the article, i always try to change the user styles a bit to make it more bearable.
can you tell me a bit more about this? i wanted something like this for a small api i have but ended up using marshmallow to validate jsons against defined schemas which i think is a bit overkill.
