It worked, but there was one major problem that brings my review down. Unfortunately, this degrades the performance of the browser considerably, and I'm not sure why.

Otherwise, it worked, some pages needed some tweaking, but I was okay with that.

Просто лучший! И работает отлично!

Perfect for documentation work. thank you .

shortcuts with the extension is not working for me

Tout est modifiable, fonctionne sur tous les sites que je consulte et pour tout ce qui est dans GDrive (doc, sheet...).
La seule page qui reste en thème clair est la page des extensions (ici-même ^^)
Ne cherchez plus de Dark Theme ou quoique ce soit sur Firefox, vous avez trouvé (;

Unfortunately, it sometimes creates noticeable performance problems

Best extension.... 10/10

Good idea!

Slows some things down like the initial load of gmail. Artifacts on some things. Ex. the banners at the top of testout.com after logging in.
