Works! Had some trouble getting it to open up but I found what I needed to do on the Stylebot Github

works very well and does what it says, might take some learning to understand how it works but after that its amazing. 5 stars

Imagine making your own dark mode version of a website that doesn't have it. This add-on is amazing.

Great Extension! One thing i would wish is a more structured font-management.

it feels pretty chaotic insering all fonts in just one line.
Maybe also integrate custom categories for the fonts.

I never write reviews. But this extension is gold. I created account just to say thank you.
