🐺 Photon Australis

Bringing sexy curves back to Firefox Photon AND Proton.

Why?

Because all you sexy Firefox users deserve something sexier than ugly, blocky square. (Who wants to be square, right?)

⚠ Support note ⚠:

This is a NEW release that supports Firefox Proton (version 89+). If you are running an older version of Firefox with Photon, please visit this link.

This is regular used and tested by me in these following configurations:

1. Firefox Developer Edition on Dark Theme + Windows 10 on Dark Theme.
2. Firefox Developer Edition on Default Theme + MacOS on Dark Theme.

😍 How do I get this sexy thing? 😍

Since Firefox 57+, the only way to customize your browser UI is through userChrome.css. Learn more here.

General Instructions:

1. Go to your Firefox browser, type about:config in your url bar.
2. Search for toolkit.legacyUserProfileCustomizations.stylesheets and set it to true
3. Type about:profiles in your url bar.
4. Under the profile that is in use (The message is something like This is the profile in use and it cannot be deleted.), click Open Folder on the Root Directory row.
5. If that folder does not have a chrome folder, create a folder, name it chrome.
6. In the chrome folder, create a file named userChrome.css
7. Determine what Firefox theme you are using:
   1. Click the icon with 3 lines on the top right corner to open the context Menu.
   2. Select Customize.
   3. At the bottom left of your screen, select Themes.
   4. Choose or determine which theme you want to use, they can either be Dark, Default, or Light.
8. Copy and paste the code that matches your Firefox theme: Dark, Default, Light into your userChrome.css file that you have created.
   WARNING: Newer versions of Firefox with Mojave or Windows 10 Dark Mode will cause Firefox to use the Dark theme by default. In this case, you should use the userChrome-dark.css theme.
9. Restart Firefox and enjoy some sexy curves :D

Special Instructions for Default Theme users:

If you are using the Default Theme but your MacOS is using the Dark Theme, you can go to about:config -> search for ui.systemUsesDarkTheme and ADD (click the '+' sign) a Number. Set the value to 0. Restart the browser.

😞 Something is broken 😞

Fell free to create an issue and I'll see what I can do. However, I'm unable to guarantee quick (or any) responses as this project is in maintenance mode.

Nothing has changed for me

Make sure that your file extension for userChrome.css is correct. Most likely a problem for Windows, refer to this issue.
