A Firefox theme made by Agnihotra Nath to simulate Safari on macOS Big Sur 11. Works best on Proton. Based on vinceliuice's WhiteSur-Gtk-Theme, we have taken inspiration from his code, to implement certain features. A big shoutout to all the WhiteSur developers, without whom, WhiteSur wouldn't exist!
- Theme made by Agnihotra Nath with inspiration from WhiteSur-Gtk-theme.
- Installation scripts made by Javier Latorre with the help of Lubzz.
