Thunderbird Installation Guide

Ubuntu 24.04 ships Thunderbird as a Snap by default.
Many users prefer the classic .deb package for faster startup, better integration, and no Snap overhead.

Open a terminal

Add PPA

sudo add-apt-repository ppa:mozillateam/ppa

Give Mozilla packages higher priority

echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox

Update
```
sudo apt update
```
Remove Snap version (if installed)
```
sudo snap remove thunderbird
```
Install
```
sudo apt install thunderbird
```

→ You now have a proper .deb install (usually latest ESR or newer)
Regular updates via sudo apt upgrade

Visit thunderbird.net
Download → Linux → .tar.bz2
Extract (example: /opt/thunderbird or ~/thunderbird)

Run

cd /path/to/thunderbird && ./thunderbird

Auto-updates via Help → About Thunderbird → Check for Updates

sudo snap install thunderbird

Pros: Very easy, automatic updates
Cons: Slower startup, higher disk usage

Install Flatpak
```
sudo apt install flatpak
```

Add Flathub

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Install

flatpak install flathub org.mozilla.Thunderbird

Run
```
flatpak run org.mozilla.Thunderbird
```
