Forked from Firefox-UI-Fix (Lepton)
- macOS style translucent blur effect is applied.
- The gray background is removed from the URL & search bar. It appears when you hover on the toolbox.
- The tab close button from inactive tabs are hidden. You can hover over the tab to make it appear.
- Favicons are hidden from the bookmarks bar.
- Most parts of the UI are center-aligned.
- New tab page is cleaner.
Below is the original README.

🔔🔔 Does the theme not work after installation?
You should copy user.js
file before the theme works.
The option system depends on user configuration, and nothing applies without settings.
Also, real-time changes are difficult because of technical limitations and require a restart.
Some settings can be conflicted and should be explicitly set to false
.
🔔🔔 Is your Firefox version v102
or lower?
You have to set userChrome.compatibility.accent_color
to true
additionally.
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!!
