This theme goal is to create a compact mode that follows Firefox 89 (known as Proton) design system while using the same vertical space as the compact mode in Firefox 88 (known as Photon).
I try to test my script in the platforms listed below. However, that doesn't mean it's bug free. If you find an issue, please open a bug report.
- Linux
- macOS Catalina
- Windows 10
- Window 7
Note: Currently I only tested it in Nightly but I plan to support both the Release and ESR channel in the (near) future.
