This is a step by step beginner’s guide shows how to install LibreWolf web browser in all current Ubuntu releases, including Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04, 25.10 and 25.04

LibreWolf is a free and open-source web browser fork from Firefox. The browser focuses on privacy and security, and has uBlocker ad blocker out-of-the-box.

The browser website has an official guide for installing in on Debian and Ubuntu based systems. This tutorial is just a re-write with screenshots and more explanations.

UPDATE: You can now install LibreWolf in Ubuntu via 2 ways:

• native .deb package from apt repository.
• Flatpak package that runs in sandbox environment.

Both are official! Choose either one that you prefer.

Option 1: Install LibreWolf Deb package

First, press Ctrl+Alt+T on keyboard to open up a terminal window. When it opens, run command below to install extrepo:

sudo apt install extrepo

Refresh cache (sudo apt update) if it failed, and use the tool to set up librewolf apt repository for Ubuntu.

sudo extrepo enable librewolf

The command will automatically add the repository by creating extrepo_librewolf.sources file into source list, and adding a key file under /var/lib/extrepo/keys.

After that, refresh cache by running command:

sudo apt update

It should print something like Get/Hit:x https://repo.librewolf.net librewolf InRelease in the output.

Finally, install the Deb package of the browser:

sudo apt install librewolf

Option 2: Install LibreWolf via Flatpak package

The LibreWolf web browser now offers Linux package through Flatpak, which runs in sandbox environment. It works in most Linux and supports amd64 (Intel/AMD) and
arm64 (e.g., Raspberry Pi) platforms.

Linux Mint 21/22 and Fedora (with 3rd party repository) enabled may search & install the package either from Software Manager or GNOME Software.

While Debian and Ubuntu may run the commands below one by one to install:

First, open terminal (Ctrl+Alt+T) and run command to ensure Flatpak daemon is installed:

sudo apt install flatpak

For old Ubuntu 18.04, try adding this PPA for the daemon package.

Then, run command to install the web browser as Flatpak package:

flatpak install https://dl.flathub.org/repo/appstream/io.gitlab.librewolf-community.flatpakref

NOTE: If the app icon is not visible after installation, either log out and back in to apply variable change, or run the command below to start it from terminal:

flatpak run io.gitlab.librewolf-community

Update LibreWolf

For the Deb package installed from apt repository, simply use Software Updater to check & install updates, or re-run the last 2 commands in option 1 instead regularly.

To check and install updates for the Flatpak package, just run command:

flatpak update io.gitlab.librewolf-community

For choice, you may install Warehouse, a graphical app to manage (include updateing) Flatpak packages.

Set LibreWolf as default web browser

For the default GNOME Desktop, open Settings (Gnome Control Center), then navigate to Default Applications in left pane. Finally, select “LibreWolf” from the drop-down box for Web.

For GNOME 46 (Ubuntu 24.04) and later, Default Applications has been moved to “Apps” settings page.

Other desktops may have their own option to do the job. If you don’t know where to find the option, try editing the config file that works in most desktop environments. To do so:

• First, open file manager and press Ctrl+H to show all hidden files and folders.
• Navigate to .config sub-folder and click edit mimeapps.list file.
• Finally, set librewolf.desktop for text/html, x-scheme-handler/http, x-scheme-handler/https and save file.

How to Remove LibreWolf Web Browser

To remove the Deb package, simply open terminal (Ctrl+Alt+T) and run command:

sudo apt remove librewolf

And, you may run the command below to disable the apt repository:

sudo extrepo disable librewolf

As it only disables the repository but keep the source and key files, you may optionally run the command below to completely remove them:

sudo rm /etc/apt/sources.list.d/extrepo_librewolf.sources /var/lib/extrepo/keys/librewolf.asc

To remove flatpak package, open terminal and run command:

flatpak uninstall --delete-data io.gitlab.librewolf-community

Also run command flatpak uninstall --unused to remove useless runtime libraries.

That’s all. Enjoy!

This simple tutorial shows how to install brave browser via the new apt source policy in Ubuntu 24.04 & 22.04.

Due to security issue, Debian changed its policy for adding apt sources. Ubuntu is changing the rules too. Since Ubuntu 22.04, it uses more secure key files with digital signature for system repositories and PPAs.

Since Ubuntu 23.10,  it now uses deb822 .sources file instead of the previous .list file for third-party repositories. And, the new source files include ‘Signed-by’ section to specify the key file.

Step 1: Install curl command line download tool

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install curl and apt-transport-https package:

sudo apt install apt-transport-https curl

Type user password (no asterisk feedback) when it asks.

Step 2: Download & Install the key

Then, run curl command to download the key file and save it into /usr/share/keyrings folder.

This can be done by running the single command below in terminal:

sudo curl -fsSLo /usr/share/keyrings/brave-browser-archive-keyring.gpg https://brave-browser-apt-release.s3.brave.com/brave-browser-archive-keyring.gpg

Step 3: Add the brave apt source repository

The previous .list file with or without ‘Signed-By’ is still working! But here I’m going to show the new .sources file.

1. First, run command to create a .sources file under ‘/etc/apt/sources.list.d’:

sudo gedit /etc/apt/sources.list.d/brave-browser-release.sources

Replace gedit with gnome-text-editor for Ubuntu 24.04.

2. Then in the pop-up text editor window, paste following lines:

Types: deb
URIs: https://brave-browser-apt-release.s3.brave.com/
Suites: stable
Components: main
Architectures: amd64
Signed-By: /usr/share/keyrings/brave-browser-archive-keyring.gpg

As you see, the new source file is easy to read, but a bit hard to write for beginners. See this thread for more about it.

Step 4: Update cache & install Brave Browser

After saving the file in last step, you can now run commands below to refresh the system package cache:

sudo apt update

And, finally install the web browser via command:

sudo apt install brave-browser

You don’t have to run the command every time when a new release is out. Just launch “Software Updater”, newer release of the browser package will be available there along with system package updates.

Uninstall Brave:

To remove brave browser package, open terminal (Ctrl+Alt+T) and run command:

sudo apt remove --autoremove brave-browser

And remove the apt source repository by running command:

sudo rm /etc/apt/sources.list.d/brave-browser-release.list

Also remove the key file via command:

sudo rm /usr/share/keyrings/brave-browser-archive-keyring.gpg

Finally, run sudo apt update to refresh system package index.

PHP finally released 8.2.0 release after 7 release candidates. Here are the new features and how to install guide for all current Ubuntu LTS.

PHP 8.2.0 allows to mark a class as readonly, which will add the readonly modifier to every declared property, and prevent the creation of dynamic properties. Moreover, using the AllowDynamicProperties attribute on readonly class will trigger a compile-time error.

Other release highlights in PHP 8.2.0 include:

• Disjunctive Normal Form (DNF) Types
• New stand-alone types: null, false, and true
• New “Random” extension
• Constants in traits
• Deprecate dynamic properties

There are as well numerous bug-fixes and other changes in the release. See the changelog for details.

How to Install Php 8.2 in Ubuntu:

Not recommended for beginners. Only install PHP 8.2 for web developing purpose or there’s specific feature or bug-fix you need in this release.

The popular Ondřej Surý’s PPA has built the package for all current Ubuntu LTS: Ubuntu 18.04, Ubuntu 20.04 and Ubuntu 22.04.

1. First, open terminal or connect to your Ubuntu server and run command to add the PPA:

LC_ALL=C.UTF-8 sudo add-apt-repository ppa:ondrej/php

Run sudo apt install software-properties-common in case the command does not exist. And, type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Then, install Php packages accordingly. For example, install apache2 module and mysql module via command:

sudo apt install php8.2 libapache2-mod-php8.2 php8.2-mysql

Or install the FPM-CGI binary for use with Nginx:

sudo apt install php8.2 php8.2-fpm php8.2-mysql

For Ubuntu 18.04, run sudo apt update first to refresh package cache.

After installed it, remember to configure your http server (apache 2 or nginx) for the new PHP package, and configure php8.2 via files under ‘/etc/php/8.2/’.

Uninstall Php 8.2

To remove the package, simply run command:

sudo apt remove --autoremove php8.2 libapache2-mod-php8.2 php8.2-*

And remove the Ubuntu PPA via command:

sudo add-apt-repository --remove ppa:ondrej/php

Remember Midori? The lightweight web browser that was default in Elementary OS and Bodhi Linux revived!

Midori was a popular lightweight web browser used the WebKitGTK rendering engine and GTK UI toolkit. The development of the project was however discontinued more than 3 years ago. And, Ubuntu even removed it from system repository since Ubuntu 22.04 LTS.

According to the Wikipedia, the Midori project has been merged with the Astian Foundation in 2019. And, Astian announced a week ago that Midori browser is still alive!

It’s now Chromium Firefox based web browser features both desktop edition for Linux, macOS, and Windows, and mobile edition for Android.

The browser still aims to be lightweight, fast and free. It’s still an open-source app, with the source code host in this Github page.

Midori web browser next generation

The new Midori browser so far features:

• New logo.
• Adblock integration, block ads out-of-the-box.
• Incognito mode support.
• Chromium based, without Google services and low resources usage
• Fast and highly customizable UI.
• Partial Chrome extensions support.
• To use its own open-source AstianGO search engine. Though, it so far uses DuckDuckGo as default. While Google, Bing, and Ecosia available for choice.

How to Install New Midori web browser in Ubuntu & other Linux

Astian offers official Midori packages for Linux through AppImage and .deb package.

Option 1: AppImage

AppImage is a portable package format without installation required. Just select download it from its website:

Then, right-click on AppImage in file manager. Open ‘Properties’ dialog and grant ‘execute as program’ permission. Finally, click run the package to launch the web browser.

Option 2: Deb package

It also provides official .deb packages for modern 64-bit computers, available to download via the link button below:

NOTE: The Debian (.deb) package seems broken at the moment of writing. It won’t install in my case in Ubuntu 22.04, Debian 11 either via double-clicking or using apt install command. So please try AppImage until Astian fixed the issue.

After downloaded the package, click open with either Ubuntu Software or App Center then install.

A new monthly release of Firefox web browser to be released soon! Users of Mozilla team PPA should already received the updates.

  sudo add-apt-repository ppa:mozillateam/ppa

• 2. Check updates for old Ubuntu releases:

  sudo apt update

• 3. Finally, install Firefox from the PPA via command:

  sudo apt install -t "o=LP-PPA-mozillateam" firefox

IMPORTANT: to avoid Ubuntu 22.04+ to override the PPA package with system built-in Snap package, you have to create a config file under ‘/etc/apt/preferences.d’, and write following rules (See this guide for details):

# Prefer Firefox package from Mozillateam PPA

Package: firefox*

Mozilla Firefox got a new monthly update recently, with minor new features, performance improvements and some bug-fixes.

According to the release note, Firefox 104 adds one more video site, Disney+, for displaying subtitles in the pop-out videos (Picture-in-Picture).

Disneyplus.com in Firefox dark

When the browser is minimized or occluded, and for background tabs, the UI will now be throttled for better performance and battery usage. And, paste unformatted shortcut now works again in plain text contexts, such as input and text area.

Other changes in Firefox 104 include:

• Various security fixes and new policies

How to get Firefox 104:

For Ubuntu 18.04 and Ubuntu 20.04, Firefox 104 has already made into official repositories, simply launch Software Updater and install the updates to get it.

For Ubuntu 22.04 with pre-installed Firefox as Snap, you should now have v104. To verify, go to hamburger menu -> Help -> About Firefox.

For Ubuntu 22.04 users hate snap package, as well as old Ubuntu 16.04, the Mozilla Team PPA maintains the latest packages. See this step by step how to install guide.

The Chromium browser package (Snap version) in Ubuntu Software is missing VAAPI hardware decoding support. Ubuntu developer team is finally working on get the feature back!

As you may know, Ubuntu now includes the chromium web browser in the system repository as Snap package that runs in sandbox. However, the package is missing the graphics hardware acceleration since version 72 which was released a few years ago in 2019.

Some third-party PPAs are being maintained with Chromium packages, either due to lack of hardware acceleration or just because they don’t like Snap.

For Chromium fans who are OK with the Snap package, you can now help testing the new hwacc build that uses the graphics card for video playback.

Install Chromium from test repository:

1.) Firstly, backup your bookmark, password etc if you’re running Chromium as Snap.

2.) Press Ctrl + Alt + T on keyboard to open terminal. When it opens, run command to remove chromium snap (if any) via command:

sudo snap remove chromium

3.) Next, install the testing build with hardware acceleration support by running command:

sudo snap install --channel candidate/hwacc chromium

Verify if hardware acceleration works:

The report page recommends to run the command below to launch chromium browser:

snap run chromium --disable-features=UseChromeOSDirectVideoDecoder --enable-features=VaapiVideoDecoder

Finally, start playing a video either by drag and dropping local file into browser window, or via video website.

And, go to about:media-internals in address bar. Click what it’s playing and find out the value of “kVideoDecoderName“.

It will be {Vaapi,VDA,Mojo}VideoDecoder if succeed, or {FFMpeg,Vpx}VideoDecoder when failed.

For Intel graphics, there’s also a command line tool to verify if GPU rendering is working.

• First, run command to install the intel-gpu-tools package:

  sudo apt install intel-gpu-tools

• The, use command to verify:

  sudo intel_gpu_top

In my case, the previous command did’t work in both i3-6006U and i5-10400 with integrated graphics card, but using the following command to launch Chromium works!

LIBVA_DRIVERS_PATH=/snap/chromium/current/usr/lib/x86_64-linux-gnu/dri/ chromium --use-gl=egl --enable-features=VaapiVideoDecoder,VaapiVideoEncoder --disable-features=UseChromeOSDirectVideoDecoder --ignore-gpu-blocklist --disable-gpu-driver-bug-workaround

How to Restore:

To remove the Chromium package, open terminal and run command:

sudo snap remove --purge chromium

And, install back the package (if you want) from stable channel either from Ubuntu Software or by running the command below in terminal:

sudo snap install chromium
