An elementary OS theme for Thunderbird

⬇️ Installation

For now theme installation is supported for:

1. 🐦 Thunderbird installed with apt package manager. Install it with command sudo apt install thunderbird.
2. 🐦 Thunderbird 📦 Flatpak version. Install it using AppCenter.

Use this one line install script to install theme. Just copy the line to your terminal and press enter:

bash <(wget --quiet --output-document - "https://raw.githubusercontent.com/Zonnev/elementaryos-thunderbird-theme/main/install.sh")

Or install theme manually:

1. Install Thunderbird in AppCenter or type sudo apt install thunderbird in the Terminal.
2. Create the chrome folder in: ~/.var/app/org.mozilla.Thunderbird/.thunderbird/<profilefolder> if you installed in the AppCenter.
3. Create the chrome folder in: ~/.thunderbird/<profilefolder> if you installed in the Terminal.
4. Download the zip file and put the base.css in the chrome folder.
5. Look which window button layout you are using and put the userChrome.css from the corresponding folder in the chrome folder.
6. In Thunderbird enter the Menu and select Settings, scroll all the way down till you see the Config Editor button. Press the button and search for toolkit.legacyUserProfileCustomizations.stylesheets and set it to true.
7. Restart Thunderbird and the theme should be applied.

🚧 Work in progress

• I have added a userChrome.css for Thunderbird Beta in the folder Thunderbird Beta theme. For now the install script overrides the files in the beta folder so make sure you add the userChrome.css manually in the chrome folder of your beta profile (usually the profile folder has -beta in the folder name).
