Hello, I downloaded firefox app on my android phone and noticed that the browser or pages are brown in color. I am not computer savvy so I don't exactly know how it arrived that way. But I love it and I would like to have it on my laptop. I have vision problems and I am photo sensitive. I eyes hurt bad, so much that tears run down my face and my nose run while trying to use the computer. Is this brown screen available for laptop. If so how would I access it. Thank you,
