Fix Firefox issue with dark GTK themes where input elements turn dark without consideration of content.

Thank you!

No, wait, the issue also mentioned putting that on :root too

@Pizzacus Yes sorry I forgot to mention; I tried that on Firefox, and for some reason the favicons (you saw it right) as well as some other non-web elements in the browser starts getting affected.
I use Firefox on Linux with a dark GTK theme.

p.s. I now have the above changes of input and textarea in my userContent.css of my firefox profile, and I haven't seen major problems since

[Pizzacus]

Wait, the favicons? Do you have a screenshot of it? That sounds like quite a peculiar case...

@Pizzacus refer back to issue #17
I have added a screenshot
