This version allows users to test upcoming features and improvements before integrating them into the stable release. This introduction will provide an overview of Firefox Beta.
- Purpose: Firefox Beta is designed for users who want to preview and test the latest features, improvements, and bug fixes before they are released to the general public.
- Update frequency: Firefox Beta is updated approximately every four weeks, offering a relatively stable testing environment.
- Notable changes: Some key updates in Firefox Beta include performance improvements, enhanced privacy features, and new developer tools.

Section 1: Import Firefox Beta PPA
Before diving into the process, it’s important to note that installing Firefox Beta will replace the default version of Firefox currently installed on your Linux Mint system. To get started, follow the steps below:
Step 1: Check your current Firefox version
First, check the version number of your existing Firefox installation by running the following command in the terminal:
You should see an output similar to this:
Mozilla Firefox xx.x
Step 2: Import Mozilla Team Firefox Next (Beta) PPA
To import the Mozilla Team Firefox Next (Beta) PPA into your sources list, execute the following command:
sudo add-apt-repository ppa:mozillateam/firefox-next -y
Step 3: Set up APT Pinning
Linux Mint’s default repository outranks the beta version you’re attempting to install from the PPA. To resolve this, you’ll need to set up APT Pinning. Follow the steps below to create and modify the preferences file:
Step 1: Create the preferences file if it does not exist:
sudo touch /etc/apt/preferences
Step 2: Add the APT Pinning rules using sed:
Execute the following commands to add the required APT Pinning rules:
echo -e "Package: *\nPin: release o=linuxmint\nPin-Priority: 700\n" | sudo tee -a /etc/apt/preferences echo -e "Package: firefox\nPin: release o=LP-PPA-mozillateam-firefox-next\nPin-Priority: 900\n" | sudo tee -a /etc/apt/preferences echo -e "Package: *\nPin: release o=Ubuntu\nPin-Priority: 500\n" | sudo tee -a /etc/apt/preferences
These commands will append the necessary APT Pinning rules to the
/etc/apt/preferences file. By using the
sed command in this manner, you can avoid manually editing the preferences file while still achieving the desired result.
Confirm this by running the following command:
If the APT Pinning rules were set up successfully, you should see the following:
