Introduction

Proton is Firefox's new design, starting from Firefox 89.
Photon is the old design of Firefox which was used until version 88.

Proton's overall feel is good, but there were a few things I didn't like and wanted to improve.
That's why this project was born, and Lepton to denote light theme layer.

Disclaimer: It works on Firefox 89 and above!!

WHY Proton?

I think a lot has improved.

(Proton's design ⬆️)

• Neatly organized menu
• Icon beautiful enough to remind you of Edge
• Nice color scheme
• Satisfied Rounding
• Modal window & Scrollbar!!

WHY Not Proton?

However, there are also many flaws.

(Photon's design ⬆️)

• Is it a tab or a button?
• Where are the menu icons?
• Icons in ActivityStream are too small
• Padding gaps are wide
• ⚠️ Address bar 3-point menu, screenshot moves to toolbar (can't fix)

Padding Comparisons

• Photon (Quantum)
• Proton
• Lepton
