In Ubuntu 22.04 Canonical made the decision to make Firefox a Snap and not a traditional package installation. This results in a slower experience as well as some integration issues with Gnome.
Open a terminal and perform the following commands.
To fix this, uninstall the Snap:
sudo snap remove firefox
Add the Mozilla repository:
sudo add-apt-repository ppa:mozillateam/ppa
Press an Enter key to complete the repository import.
Copy the following as a single line and run it in the terminal to change the installation priorities to favor the Firefox DEB file.
echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox
Update your repositories:
sudo apt update
Install Firefox:
sudo apt install firefox
