🔔🔔 Does the theme not work after installation?

You should copy [[./user.js][ ~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 [[./docs/Restrictions.md#supports][technical limitations]] and require a restart.

Some settings [[https://github.com/black7375/Firefox-UI-Fix/wiki/Options#using-userjs][can be conflicted]] and should be explicitly set to =false=.

-----

🔔🔔 Is your Firefox version =v102= or lower?

You [[https://github.com/black7375/Firefox-UI-Fix/wiki/Compatibility-Issues-Solution#accent-color-at-v102-or-lower][have to set]] =userChrome.compatibility.accent_color= to =true= additionally.

** Introduction
  [[https://wiki.mozilla.org/Firefox/Proton][Proton]] is Firefox's [[https://acorn.firefox.com/][new design]], starting from Firefox 89. \\
  [[https://firefoxux.github.io/photon/][Photon]] is the old design of Firefox which was used until version 88.

  Proton's [[#why-proton][overall feel is good]], but there were a few things I [[#why-not-proton][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.

   [[https://user-images.githubusercontent.com/25581533/119773764-a6639e00-beb0-11eb-8023-498b6293c4b2.png]]

   (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.

   [[https://user-images.githubusercontent.com/25581533/119773812-b5e2e700-beb0-11eb-923c-55ae1a8ca249.png]]

   (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
