Simple dark theme for Facebook Messenger.

DEPRECATED! Messenger.com now has a native dark mode, so you don't need this anymore. See https://github.com/jerry1100/messenger-dark-theme?tab=readme-ov-file#messenger-dark-theme-deprecated

Old description:
Another dark theme for Messenger? Yes, but here's why you should use this over the others:
1. It looks the best. It's clean, minimalistic, and the colors work well.
2. It's modern and well-maintained. Post an issue and I'll likely resolve it within a few days.
3. The code is simple and it's open-source. All this does is add styles to override Facebook's styles. No JavaScript, no tracking, 100% secure.

Works immediately after installing."
