Fixing Huge Emoji Icons in Thunderbird (Ubuntu 18.04)
Sometimes, emojis in Thunderbird appear too large. This is usually due to font size mismatches between Thunderbird and your system fonts.
Step 1: Install the Noto Color Emoji Font
Use the terminal to install the font:
sudo apt install fonts-noto-color-emoji
Step 2: Clear the Font Cache
fc-cache -fv to apply the changes.
Step 3: Restart Thunderbird
Your emojis should now appear normal.
Linux Desktop in 2026
- Wayland: Most modern distros (Ubuntu 22.04+, Fedora) now use Wayland by default. Emoji rendering on Wayland is handled by the client (application), reducing collision with system settings.
- Flatpak Apps: If you use the Flatpak version of Thunderbird, ensure it can access system fonts:
flatpak override --filesystem=~/.local/share/fonts.
