install mozilla repository ubuntu

To install Mozilla's official APT repository and get the native .deb version of Firefox on Ubuntu (bypassing the default Snap package), create a keyrings directory, import Mozilla’s GPG key, add the repository source, configure package priority pinning, and install using apt. Follow the detailed instructions provided by Mozilla Support to set this up safely. [1, 2]

Remove Snap and Block Resubmission

Remove the existing Firefox snap package:
sudo snap remove firefox
Block Ubuntu from reinstalling the Snap via the transitional package:
sudo tee /etc/apt/preferences.d/mozilla > /dev/null << EOF
Package: firefox
Pin: release o=Ubuntu
Pin-Priority: -1
EOF [1]

Add Mozilla's Official Repository

Create the keyrings directory:
sudo install -d -m 0755 /etc/apt/keyrings

Import the signing key:
wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null
Add the repository to your sources list:
echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee /etc/apt/sources.list.d/mozilla.list > /dev/null [1, 2]

Prioritize and Install

Set high priority for Mozilla's repository:
sudo tee /etc/apt/preferences.d/mozilla-priority > /dev/null << EOF
Package: *
Pin: origin packages.mozilla.org
Pin-Priority: 1000
EOF
Update and install Firefox:
sudo apt update && sudo apt install firefox [1, 2]
