For those who are sticking to Firefox ESR, the latest 115 release is now easy to install in all current Ubuntu releases via PPA.

Firefox ESR (Extended Support Release) is a slow moving release series target for organizations, including schools, universities, businesses. It has different release circle compare to the general Firefox series.

Mozilla keeps updating the ESR with stability, security fixes and policy updates every few weeks,  and rolls out major updates on average every 42 weeks. See update differences between  Firefox ESR and Rapid releases.

The latest version now is Firefox ESR 115.x, which was firstly released almost 2 months ago. It includes all the new features since Firefox 102. But of course lacks features in v116, 117, and next releases until  they are included in next major ESR release. See the release note for details.

Like the rapid releases, you can download the latest Firefox ESR as portable tarball from the ftp page. However, PPA is a good choice with better Ubuntu integration and easily to keep it up-to-date. It’s also a good alternative for Ubuntu 22.04+ users who hate Snap packages.

For Ubuntu 22.04 (and old Ubuntu 16.04), you may install Firefox 100 as .deb from Mozilla Team PPA (Need to set PPA priority, see HERE for more).

Ubuntu 22.04 finally removed the .deb package for Firefox web browser from it’s repository! Here’s how to install it back.

As you may know, Firefox in Ubuntu repository since 22.04 is a Snap package that runs in sandbox. It’s easy to remove it. But when you try installing the deb package via apt, it just install the Snap version back!!

Like Chromium, the Firefox deb in Ubuntu 22.04 + repository is an empty package that links to the Mozilla’s official Snap.

And, if you want to install the latest Firefox using the classic .deb package format, there are 2 easy ways:

• Mozilla Team PPA maintained by Ubuntu Team members.
• Mozilla’s new apt repository maintained by Firefox developer team!

(Optional) Remove the pre-installed Firefox Snap

It’s OK to keep the default Snap package. But it will cause duplicated Firefox icons after installing Firefox in .deb package format.

NOTE: Export bookmarks and backup other important data before removing it!

To remove it, press Ctrl+Alt+T on keyboard to open terminal. Then, run the command:

sudo snap remove firefox

Also, remove the empty Deb package by running command:

sudo apt remove firefox

Option 1: Install Firefox via “Mozilla Team” team PPA

The team described that it has assumed responsibility for Ubuntu’s official Firefox and Thunderbird packages.

And, the Firefox and Firefox ESR package maintainer for “Mozilla Team” team PPA, Rico Tzschichholz, is a well-known Ubuntu user who also maintains the official packages for LibreOffice, Plank dock, and unbound DNS server.

1. Add Mozilla Team PPA

In terminal (Ctrl+Alt+T), run the command below to add the PPA. Type user password (no asterisk feedback) when it asks and hit Enter to continue.

sudo add-apt-repository ppa:mozillateam/ppa

As the PPA description indicates, the PPA was previously created for Firefox ESR and Thunderbird. It now contains the latest Firefox too.

2. Set PPA priority:

The empty Firefox deb in Ubuntu’s official repository has version number 1:1snap1-0ubuntu2. It’s always higher than the PPA package version. Running package updates either via sudo apt upgrade or ‘Software Updater’ will automatically install the official one which redirects to Snap.

To workaround the issue, you have to set a higher PPA priority. To do so, run the command below in terminal (Ctrl+Alt+T):

sudo gedit /etc/apt/preferences.d/mozillateamppa

For Ubuntu 24.04, replace gedit in command with gnome-text-editor, or use nano that works in all the desktop environments.

The command creates and opens empty config file in Gedit text editor. When it opens, add the lines below and save it:

Package: firefox*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001

For nano text editor, press ctrl+s to save file, and ctrl+x to exit.

After saving the file, run sudo apt update command in terminal to apply changes.

sudo apt update

3. Install Firefox via apt

Tip: the commands in this step also installs Firefox for the old Ubuntu 16.04. Though sudo apt update need to be run first.

Finally, run the command below to install the latest Firefox package as deb:

sudo apt install firefox

Here -t 'o=LP-PPA-mozillateam' specifies to install Firefox from that PPA. It’s required until you set higher PPA package priority (see next step).

The -t 'o=LP-PPA-mozillateam' flag is no longer required after setup PPA priority.

For choice, you may install Firefox ESR instead. It’s another official Firefox package that moves slowly and targets for school or enterprise use.

sudo apt install firefox-esr

Option 2: Install Firefox via its official repository

Mozilla’s new apt repository contains 4 versions of Firefox packages: Firefox Stable, Firefox Beta, Firefox Development Edition, and Firefox Nightly. It’s a good choice for Ubuntu & Debian users.

1: Get Repository Key file

To add the new repository, you need to first download & install the key, so your system will trust the packages from it.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to make sure ‘/etc/apt/keyrings’ exist for storing the keys.

sudo mkdir -p /etc/apt/keyrings

Then, download & install the key by running the single command below in terminal:

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

After that, you can verify the new key file by listing the content of that directory via command ls /etc/apt/keyrings.

2: Add Mozilla’s apt repository

Also in a terminal window, run the single command below will create a config file and write the source repository.

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee /etc/apt/sources.list.d/mozilla.list > /dev/null

When done, you may verify by running cat /etc/apt/sources.list.d/mozilla.list to print the source file content.

3. Set apt repository priority:

Also you need to set higher priority for Mozilla’s repository, so Ubuntu will install Firefox from it rather than the snap package.

To do so, run command to create & edit the config file:

sudo gedit /etc/apt/preferences.d/mozilla

Also, replace gedit with gnome-text-editor for Ubuntu 24.04, or use nano command line editor that works in most desktop environments.

When file opens, add following lines and save it (For nano, press ctrl+s to save, and ctrl+x to exit).

Package: firefox*
Pin: origin packages.mozilla.org
Pin-Priority: 1001

4. Install Firefox:

Finally, refresh your system package cache by running command in terminal:

sudo apt update

And, install Firefox from that repository via command:

sudo apt install firefox

You may also use firefox-beta, firefox-devedition, or firefox-nightly in last command to install other versions.

How to Restore Firefox Snap:

To restore the pre-installed Snap package, or uninstall the .deb package, first remove the repositories:

• To remove the Mozilla Team PPA, launch ‘Software & Updates‘ utility and navigate to Other Software tab, finally remove the corresponding source line.
• To remove the Mozilla apt repository, simply delete the source file, by running command in terminal:

  sudo rm /etc/apt/sources.list.d/mozilla.list

After that, either launch Software Updater to upgrade Firefox or use apt commands below. Both of which will automatically install back the pre-installed Snap package.

sudo apt update

sudo apt install firefox

That’s all. Enjoy!

On the first launch of Firefox 94, a dialog will pop-up allows you to choose between color schemes. By clicking on “Explore colorways“, it allows to choose between 6 color palettes with live preview. And each has ‘Soft’, ‘Balance’, and ‘Cold’ colors to choose from.

For those using Mesa driver >= 21, Firefox 94 now uses the Linux graphics stack EGL instead of GLX. This will increase WebGL performance and reduce resource consumption. Ubuntu 21.04 and Ubuntu 21.10 may have the benefit, though proprietary Nvidia driver is not supported at the moment.

The new Firefox introduced a “about:unloads” page, allows users to manually unload inactive tabs to release system resources. Though it can be disabled by settings “browser.tabs.unloadOnLowMemory” to false.

Get Firefox 94:

For all current Ubuntu releases, including Ubuntu 18.04, Ubuntu 20.04, Ubuntu 21.04, and Ubuntu 21.10. It recommends to wait until the official Ubuntu builds released (check here).

It will be available to install in next few days through “Software Updater”:

For the portable Linux tarball as well as release note, go to mozilla website.

The “Software Updater” utility in Ubuntu MATE 21.10 tries to remove native Firefox package and install the SNAP version instead. If you’ve done that, here’s how to revert to Firefox DEB package and prevent the misbehavior.

As you may know, Ubuntu is switching Firefox from native DEB to the universal SNAP package. Ubuntu 21.10 now has Firefox SNAP out-of-the-box, while its flavors are still having the classic deb package.

However, in Ubuntu MATE 21.10 the “Software Updater” has a bug. It tries to remove pre-installed Firefox package by marking it as “Duplicate packages to be removed”.

Software Updater Tries to Install Firefox SNAP

If you clicked “Install Now” button without attention. The default Firefox web browser will be replaced with the SNAP app:

Revert to pre-installed Firefox DEB:

By going to the app “menu -> Help -> About Firefox” will tell if you’ve done that mistakenly.

The Firefox SNAP app

And, you may press Ctrl+Alt+T on keyboard to open terminal, and run command to remove the Snap if installed:

sudo snap remove --purge firefox

Then install the native Firefox deb package by running command:

sudo apt install firefox

Prevent Software Updater from installing Firefox Snap:

Thanks to N0rbert, run the single command below in terminal to do the trick until the upstream fixed the bug.

sudo apt-mark manual firefox

The command will work on all Ubuntu flavors, though I found the issue only in Ubuntu MATE so far.

That’s it. Enjoy!

Mozilla Firefox 93.0 was officially released today. The release features AVIF image support and further security improvements.

The AV1 image format (AVIF) is an image file format for storing images or image sequences compressed with AV1 in the HEIF file format. It offers significant file size reduction compare to JPEG, PNG and WebP. Google Chrome added it support since version 85. By releasing v93.0, Firefox now has AVIF image support.

Some PDF files have interactive fields to fill in data. Since Firefox 83, the built-in PDF viewer supports filling fields such as text, check boxes, and radio buttons. In the new release, it adds more forms (XFA-based forms, used by multiple governments and banks) support.

Firefox PDF viewer filling forms

To protect against potentially malicious or unsafe downloads, Firefox now blocks insecure HTTP downloads on a secure HTTPs web page, and blocks downloads in sandboxed iframes, unless the iframe is explicitly annotated with the allow-downloads attribute. Though, an option is available to select download anyway.

Other changes in Firefox 93 include:

• Automatically unload tabs on Windows, when system is running out of memory.
• Prompt to finish installation for macOS users first time running Firefox from a mounted .dmg file.
• Improved SmartBlock and new Referrer Tracking Protections.
• Fixed working with Orca screen reader.
