Improvement: Single installation script

[jacksongoode]

I believe it would be possible, but if there is a way to configure a user's Firefox config through their profile via a single script, it would be far easier to set up at least the options for this theme. I would also recommend using this utility for your users to apply your theme more simply https://github.com/ryanccn/nyoom

Oh that's nice.

If that tool can auto-apply Sidebery configs, I will add nyoom-related guide on the Readme, otherwise I'll just leave it as it is 🙏
