Doki Theme for Firefox od Unthrottled

- Restored `Device Match` functionality for Firefox v100+.

**6 New Light Themes!**

- Tired & broken down programmers rejoice! Even though you will never be pampered by a real Fox-demigod, you can now at least code with one. Let "The Helpful Fox Senko-san" watch over you as complete your tickets. You can almost feel the "おかえりなのじゃ" you will never get 😭
- I decided to complete my Quintessential Quintuplets collection by adding the oldest and youngest quint: Nakano Ichika & Nakano Itsuki.
- Tomori Nao, from Charlotte, has an interesting dichotomy when it comes to her personality. She is super cute tho.
- Have I ever seen Code Geass? No. Can I appreciate C.C. without having seen the anime? Yeah buddy.
- Guess while I'm talking about "anime I haven't seen but, chose to make a theme because the girl is pretty." We now have Yuzuriha Inori from Guilty Crown.

**4 New Dark Themes!**

- I can already hear you now, "Rimiru Tempest, from 'That Time I Got Reincarnated as a Slime', is not a boy. They are the best genderless slime, get your facts correct." Yeah well....shut up.
- Next, is one of the S ranked heroes in the 'One Punch Man' universe, Genos.
- After that, is the smug smile of Yukihira Soma from Shokugeki no Soma.
- Lastly, I am going to be honest, I haven't seen Haikyu. I just wanted a Indigo & Orange based theme. So here is Hinata Shoyo.
