For this case, we will use Ubuntu 17.10, and we must bear in mind that the existing Firefox installation will be updated to an unstable version of Quantum.

A series of add-ons and existing extensions will not work in the newer version. It is possible to remove Quantum and return to Firefox 56 by rerunning its installation.

Mozilla has an official PPA to test the beta version. We can use the same PPA to install Firefox Quantum.

For this we will execute the following line:

sudo add-apt-repository ppa:mozillateam/firefox-next

Once the official PPA has been downloaded, we proceed to update the packages by running the line:

sudo apt update

sudo apt remove firefox
sudo add-apt-repository --remove ppa:mozillateam/firefox-next
sudo apt install firefox

So we will be again with the stable version of Mozilla Firefox.

Mozilla has improved Firefox Quantum so that the tab that we use actively is downloaded and executed before other tabs that are in the background.
