If Facebook provides their own dark theme, then I'd love to thank everyone who used and contributed to this extension and it was fun while it lasted! If there is still no native night theme supported, I will try my best to re-establish functionality within 1-2 weeks or so. Please understand that it may take some time. Cheers, love you all.
