This project will be superseded by a more complex Firefox theme of the same name by different developers. Therefore, this repository has been renamed to Phroton Legacy and archived.

Make Proton look like Photon.

This is a userChrome.css file that will restore the old Firefox UI on newer versions.

In order for icons to display properly, you must enable svg.context-properties.content.enabled in about:config. (This is the case on FF91, but it doesn't seem to be so true around FF102)

Since Firefox 106, private browsing may be separated into multiple windows. If you desire the old behaviour, disable browser.privateWindowSeparation.enabled.

• No arrows on popup menus on versions around Firefox 100
• Directly changing uidensity through about:config requires a restarted browser session in order to adjust omnibox scaling. This does not occur through the Customise Firefox page.
• Most popup menus need to be reworked for Photon style.
• Download button animations need to be replaced.
• Built-in dark theme has wrong icon colours on main toolbar
• A few other minor issues (button dimensions, etc.)
