Installation

There are 3 ways of installing this theme.

Manually 🛠
As an Extension 🧩
Using Git

Manually 🛠

Can be installed on all editions of Firefox. Configuration is handled in about:config. There is no auto-updating.

Open about:config and set:

Pref	Value	Description
`toolkit.legacyUserProfileCustomizations.stylesheets`	`true`	Enables userChrome customization.
`svg.context-properties.content.enabled`	`true`	Required for proper icon coloring.
`browser.newtabpage.activity-stream.logowordmark.alwaysVisible`	`false`	Reverts the new tab Firefox logo behavior to what it was in Photon.

For Firefox 121 and below

Pref	Value	Description
`layout.css.has-selector.enabled`	`true`	Only for Firefox 121 and below. Required for some functionality to work.
`layout.css.nesting.enabled`	`true`	Only for Firefox 117 and below. Required for theming and some other stuff to work.

Optionally, you can set:

Pref	Value	Description
`security.secure_connection_icon_color_gray`	`true`	Makes the connection icon gray instead of green. Default behavior in later versions of Photon.

Too lazy to set all these prefs? You can visit https://zapsnh.github.io/zcpt-configurator/, enable Include preferences for theme installation, and click Export Options to generate a user.js file that you can put in your profile folder.

Make sure to delete the user.js file after you start Firefox so that it doesn't override any changes you make in about:config.

Download the release for your version:

🪨 Static Release (stability)	🛞 Rolling Release (features and bugfixes)
Firefox 129 (recommended)	Firefox 129
Firefox 128esr (download the ESR version)	Firefox 128esr
Firefox 115esr (download the ESR version)	Firefox Beta/Nightly

Older Versions

Extract the zip and move zapsCoolPhotonTheme-* to your profile folder which you can find by going to about:support and opening your profile folder/directory.

Rename the zapsCoolPhotonTheme-* folder to chrome

Make sure the directory is like this:

Profiles > XXXXXXXX.profile_name_here > chrome > userChrome.css and others

and not like this:

Profiles > XXXXXXXX.profile_name_here > chrome > zapsCoolPhotonTheme-* > userChrome.css and others

Restart Firefox.

You're done! 🎉

As an Extension 🧩

Can only be installed on Firefox Developer Edition, Firefox Nightly, and Firefox ESR (and forks based on ESR) since you need to disable extension signing (which may be insecure).

Has auto-updating and a built-in configurator. This version is based on Paxmod.

Open about:config and set:

Pref	Value	Description
`extensions.experiments.enabled`	`true`	Enables extensions experiments which allows CSS theming in extensions.
`xpinstall.signatures.required`	`false`	Disables extension signing which may be insecure. See this for the reason.

All other preferences required to run the theme (see the table above) will be set automatically.

Using Git

Recommended for tech-savvy people.

Can be installed on all editions of Firefox. Configuration is handled in about:config. There is no auto-updating (unless you make a script for that) but you can quickly update using git pull in your terminal.

Open about:config and set the same prefs in the Manual installation.

Download and install Git if you haven't already.

Open your profile folder which you can find by going to about:support and opening your profile folder/directory.

If you're in a file manager with a GUI (Explorer, Finder, etc.), open a terminal in the profile folder, usually by right clicking and clicking Open in Terminal (or similar). (example)

Copy (or type) this command into the terminal git clone https://github.com/zapSNH/zapsCoolPhotonTheme.git chrome and press enter. Make sure the terminal is in the profile folder (like Profiles > XXXXXXXX.profile_name_here) and not in any of its subfolders.

If you're using a version of Firefox that isn't the latest stable version then copy (or type) these commands into the terminal.

cd chrome
git checkout BRANCH_NAME

where BRANCH_NAME is your Firefox version (i.e. 115esr or nightly). (don't use the ones prefixed by webextension)

You're done! 🎉

Forks

If you're using a Firefox fork (e.g. Waterfox, Floorp, etc.), you can set these prefs in about:config for theme fixes and adjustments for your browser.

Pref	Value	Browser
`uc.waterfox`	`true`	Waterfox
`uc.floorp`	`true`	Floorp
`uc.librewolf`	`true`	LibreWolf
`uc.tor`	`true`	Tor Browser

Configuration

Config options are available at the Wiki.

An interactive configurator is available at https://zapsnh.github.io/zcpt-configurator/. To apply the settings, place the exported user.js file in your profile folder/directory (Profiles > XXXXXXXX.profile), launch Firefox, and then delete the user.js file afterwards.

For the WebExtension version, the configurator is can be found in the extension's option page (about:addons > zap's cool photon theme > Preferences/Options). The settings apply after you click Apply.

Miscellaneous

Firefox Photon icons were taken from the omni.ja file from Firefox 87. Other icons that were not in Firefox 87 were made by me.
