How to Install Floorp Web Browser in Ubuntu (Step by Step)

This is a step by step beginners guide shows how to install the Floorp web browser in Ubuntu Desktop.

Floorp is a new free open-source web browser forked from Firefox. It’s promoted as “the most Advanced and Fastest Firefox derivative”.

The browser is based on Firefox ESR. It’s updated every 4 weeks, with security updates provided before each Firefox release. It has strong tracking protection, no user tracking, flexible layout, and switchable design.

Floorp provides official Linux packages through an apt repository and Flatpak package. Advanced users can simply follow the commands in its download page. For beginners here’s a step by step screenshots as well as descriptions.

Floorp Web Browser

Option 1: Install Floorp (.deb) from apt repository

For the classic .deb package format, it provides an apt repository with Ubuntu 20.04, Ubuntu 22.04, and higher support.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command:

curl -fsSL | sudo gpg --dearmor -o /usr/share/keyrings/Floorp.gpg

curl command is NOT available out-of-the-box in Ubuntu, you may install it first via sudo apt install curl.

This command will download the key file from and save it to the /usr/share/keyrings directory. You can verify the file (should be unreadable) by running cat /usr/share/keyrings/Floorp.gpg.

2. Then run command to download the source file and save to /etc/apt/sources.list.d.

sudo curl -sS --compressed -o /etc/apt/sources.list.d/Floorp.list ''

When done, use cat /etc/apt/sources.list.d/Floorp.list to verify the file content.

3. After that, you have the apt repository as well as its key added into your system. Now, run the command to refresh system package cache:

sudo apt update

It will output something says “Hit: x…”. And, finally install Floorp web browser .deb package from that directory:

sudo apt install floorp

Option 2: Install Floorp as Flatpak package

For choice, you can install the universal Flatpak package instead. It runs in sandbox, and works in most Linux!

First, press Ctrl+Alt+T on keyboard to open terminal, then run command to enable Flatpak support:

sudo apt install flatpak

Other Linux can follow this setup guide to enable Flatpak support.

Then, most Linux user can install the browser as Flatpak package via command:

flatpak install

NOTE: The Flatpak is easy to control the folder access permission. It by default can access your Desktop, Documents, Downloads, Videos, Pictures, and Music folders. You can use Flatseal management tool to change the permissions.

Finally, search for and launch the browser from start menu (or ‘Activities’ overview) and enjoy!

Uninstall Floorp

For the .deb package, open terminal and run command to uninstall it:

sudo apt remove --autoremove floorp

Also, delete the source and key files to remove the apt repository:

sudo rm /etc/apt/sources.list.d/Floorp.list /usr/share/keyrings/Floorp.gpg

For the Flatpak package, uninstall it by running command:

flatpak uninstall --delete-data one.ablaze.floorp

Also run flatpak uninstall --unused to remove useless run-time libraries.
