This simple tutorial shows how to install the latest Firefox Nightly in all current Ubuntu releases!
Firefox Nightly is the bleeding edge version of the web browser that updates twice a day. It contains features that are still in developments months or even years before they become mainstream.
The Nightly build is more likely to crash than the stable release. For testing purpose or power-user who prefer the very latest features, here you can install Firefox Nightly via 3 ways!
Method 1: Install Firefox Nightly via Snap package
The easiest way to get Firefox Nightly is using the Snap package. It receives updates automatically, however, will override the pre-installed Firefox, by updating it to the latest edge channel.
Ubuntu 22.04 and higher users, can simply open Ubuntu Software (or App Center). Search Firefox and switch channel/source to “latest/edge”.
Or, press Ctrl+Alt+T on keyboard to open terminal. When terminal opens, run the command below instead to install Firefox Nightly:
snap refresh firefox --channel=latest/edge
NOTE: The Snap package will take use the previous profile. In the case, you can open about:profiles page, then create a new profile and set it as default.
Method 2: Use New Apt Repository
Mozilla announced new official apt repository recently. It contains the .deb package of most recent Firefox Nightly package for all current Ubuntu and Debian releases.
1. First, press Ctrl+Alt+T on keyboard to open terminal. When terminal opens, run command to download & install the key for that repository:
2. Next, add the apt repository by running the single command below:
echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.gpg] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null
This command will create the ‘mozilla.list‘ file under /etc/apt/sources.list.d directory and write the source line into it.
3. Finally, refresh the system package cache:
sudo apt update
And, install the Nightly build of Firefox from that repository by running command:
sudo apt install firefox-nightly
Method 3: Install Firefox Nightly via Ubuntu PPA
For choice, there’ a daily build PPA maintained by Ubuntu members. Which, so far supports Ubuntu 20.04, Ubuntu 22.04, Ubuntu 23.10, and Ubuntu 24.04
The PPA is a good choice, since it contains native .deb package. It will NOT override any other Firefox Stable package (neither deb nor snap), and uses its own profile for storing user data.
1. To add the PPA, first press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command:
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Linux Mint user needs to manually update the system package cache after adding PPA, though its done automatically in Ubuntu 20.04 and higher:
sudo apt update
3. Finally, install the Firefox Nightly build by running command:
sudo apt install firefox-trunk
After installing the package, launch it from ‘Activities’ overview screen or app menu depends on your desktop environments. And, you can use “Software Updater” (or Update Manager) every day to keep the package up-to-date.
Uninstall Firefox Nightly
For the Snap package, just open terminal and run command will restore to the pre-installed Firefox package:
snap refresh firefox --channel=latest/stable
However, the restored Firefox Snap will create a new user profile instead of using the original one, though you can manually backup and restore your important data.
For the apt repository package, open terminal (Ctrl+Alt+T) and run command to remove it:
sudo apt remove --autoremove firefox-nightly
To remove the source repository, just delete the source file and key by running the 2 commands below one by one:
Documentation previews for Hugging Face models and datasets
local ML-based full line code completion for JavaScript and TypeScript
sticky lines in the editor
in-editor code review
New Terminal in Beta.
And new AI assistant functionality (Pro only)
The new release is available to install in Ubuntu via different ways. They include Snap, Flatpak, official tarball, and Ubuntu PPA. Choose either one that you prefer.

This simple tutorial shows how to replace ‘Recent Used‘ with current working directory as default in GTK file chooser in Ubuntu.
Many apps use “Recent Used” as default in their “Open File” dialog. It’s great, but there’s a choice to make it default to the directory of current editing files.
GTK4 File Chooser
This is quite useful when working with many files in same directory. For example, when editing image via GIMP, press Ctrl+O (or Ctrl+Alt+O) will open file chooser and automatically open the directory of current image, instead of always ‘Recently Used’.
For GTK2 Apps
There are still some popular applications, such as GIMP, use GTK2 toolkit for their user interface.
1. First, open ‘Files’ (the file browser), press Ctrl+H to show hidden files/folders. Then navigate to .config -> gtk-2.0.
2. In that folder, click edit the ‘gtkfilechooser.ini‘ file. When file opens, change StartupMode=recent to StartupMode=cwd and save the file.
For GTK3/GTK4 Apps
GTK3 file chooser in Ubuntu 22.04/23.10 by default selects current working directory, but GTK4 chooses recent files as default. And, they have hidden option to configure this behavior.
Option 1: Use gsettings command
For those who are OK with Linux commands, just press Ctrl+Alt+T on keyboard to open a terminal window.
When terminal opens, run command to set current working directory as default for GTK3 file chooser:
gsettings set org.gtk.Settings.FileChooser startup-mode 'cwd'
For GTK4 applications, run this command instead in terminal window:
gsettings set org.gtk.gtk4.Settings.FileChooser startup-mode 'cwd'
Option 2: Use Dconf Editor (Graphical)
For graphical way, first search for and install ‘Dconf Editor‘ in Ubuntu Software:
or run command in terminal to install the tool, in case the Software App does not work for you:
sudo apt install dconf-editor
Then, search for and launch the ‘Dconf Editor’ tool:
When it opens, navigate to ‘org.gtk.Settings.FileChooser’. Finally, click ‘startup-mode’,turn off ‘Use default value’ and set custom value to ‘cwd’.
Also, navigate to ‘org.gtk.gtk4.Settings.FileChooser’ and change the value of ‘startup-mode’ to ‘cwd’ for GTK4 file chooser.
After making the changes, all your GTK file chooser dialog should use current working directory as default instead of ‘Recently Used’ immediately!
Ubuntu 23.10 with GNOME 45 has replaced the top-left ‘Activities’ with a workspace indicator. By hovering over it, you can use mouse scroll to switch workspaces.
This is done by a simple extension called “Workspace Scroll”. Like the volume icon, with that extension, you can move mouse cursor over the top-left indicator, then scroll the middle mouse button to switch workspaces (aka Windows’ Virtual Desktop).
This can be useful for mouse heavily users, since it saves you a few mouse clicks!
UPDATE: THIS BEHAVIOR NOW IS DEFAULT OUT-OF-THE-BOX!!! You don’t have to follow any tutorial, just move mouse cursor over the workspace indicator and scroll middle button.
Want to install the latest Linux Kernel 6.5? It’s there in your Ubuntu 22.04 system repository!
Linux Kernel 6.5 was released a week ago with exciting new features, including initial USB4 v2, MIDI 2.0 support, much faster parallel direct I/O overwrite on EXT4, Acer Aspire 1 Arm laptop, Sony Xperia M4 Aqua phone, open-source driver support for Lenovo ThinkPad X13s laptop, enhanced load balancing for Intel hybrid CPUs, Intel SoundWire ACE2.x support, and more.
Ubuntu built the Kernel package in the Mainline PPA, which sadly only installs in Ubuntu 23.10 so far due to dependency issue.
Now, for Ubuntu 22.04 LTS, Linux 6.5 has been made into the main repository as OEM Kernel!
What is OEM Kernel
Ubuntu LTS has a few different Kernel series. They include GA Kernel that is default in first stable release, HWE Kernel (6.2 at the moment) backported from newer Ubuntu short-term releases and default in point release (e.g., Ubuntu 22.04.1, 22.04.2).
The OEM Kernel is an Ubuntu derivative kernel, specifically for use in OEM projects.
It is a staging Kernel series with shorter life cycle. It will get rolled off to the next HWE kernel once all the fixes have been forward-ported. Meaning, Linux 6.5 will probably be the default in next Ubuntu 22.04.4.
The OEM Kernel is made and officially supported by Ubuntu Team. It’s SAFE to run in any machine according to the Wiki page.
How to Install OEM Kernel 6.5 in Ubuntu 22.04
To install the Kernel package, simply press Ctrl+Alt+T on keyboard to open a terminal window.
When terminal opens, run command to refresh package cache:
sudo apt update
Finally, install the kernel package via:
sudo apt install linux-oem-22.04d
When done. Restart your computer, and verify by running command in a terminal window:
uname -a
Uninstall OEM Kernel 6.5
To restore the old Kernel, first start/restart your machine and choose the previous Kernel (under “Advanced”) in boot menu.
In case you removed the old Kernels, install it back by running command:
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.
In the recent update of Ubuntu 23.10 daily build, the GNOME desktop has been updated to v45 beta. And, here are some visual changes.
The default wallpaper now has a dark variant. Meaning changing Ubuntu Desktop to dark style will also change to dark style wallpaper. Though, the final wallpaper is not revealed yet!
The ‘Files’, aka Nautilus file manager, has been redesigned with more stylish layout. Which, supports drag and drop web image into file, and implements Global Search.
Redesigned Nautilus File Manager
And, there’s new system extension to enhance tiling window support. Not only half screen tiling, it also support tiling window to quarter screen size, with either drag’n’drop or keyboard shortcuts, as well as features such as Tiling Pop-up and Tiling group.
By going to ‘Settings’ -> ‘Ubuntu Desktop’, you’ll see the new toggle options. Though, you can get even more by using “Extension Manager”.
Via the latest Gnome Shell package updates, the top-left ‘Activities’ button is finally replaced by an indicator. Now, it displays a white pill that indicates which workspace you’re on. Depends on how many workspaces you have, all others are indicated via gray dots.
As well, you may found the app menu, to indicate which app window is on focus, has also been removed. Though, the new Window Focus animation is not implemented at the moment.
They are even more great new features in Ubuntu 23.10. To try it out, just download the latest daily build image from the link below and install it in either real or virtual machine.
Shared Folders feature does not work for your OS in VirtualBox Virtual Machine? Here’s a quick workaround to transfer files between host and VMs.
VirtualBox has port forwarding feature that allows to access a service or an app running in VM from the host or even the internet. With it, you can setup a quick http or ftp server in VM, then access the files outside. Or, use scp command to transfer files.
Step 1: Configure Port forwarding
Firstly, shutdown your virtual machine. Then, open its ‘Settings‘. In pop-up dialog, navigate to ‘Network’ -> Adapter 1 -> Advanced -> Port Forwarding.
In next “Port Forwarding Rules” dialog, click the right-corner icons to add/remove rules. Then, set host port and corresponding guest port.
For example, if you want to SSH or SCP to VM, then add a rule and set guest port to 22 (if default SSH port in use) and set host port to whatever that’s not in use.
In my case, I want to set up a temporary Python http server, then access from the host, so I added a rule and set both host and guest ports to 8000.
Step 2: Setup a temporary http server to transfer files
Python is pre-installed in most Linux. It has a built-in script, allows to quickly setup a http server via a single command.
Just, boot your Linux Virtual Machine. Then, right-click on your desired folder and select “Open in Terminal” or “Open Terminal Here”. Finally, run command to setup a simple http server on VM:
python3 -m http.server
Finally, in host machine, open up a web browser and go to localhost:8000. Then, you can access (download) all files under that folder in the VM.
If you want to create a temporary http server with upload support, then install uploadserver module in your VM via command:
pip install uploadserver
In some Linux, you may add --break-system-packages flag. So the command will be:
pip install uploadserver --break-system-packages
Then start the http server with upload feature by running command:
python3 -m uploadserver
Finally, in host go to localhost:8000/upload to upload files to VM.
Step 3: (Optional) Use SSH/SCP
For choice, you can also use secure shell (SSH) protocol to access your VM. In the case, you need to map port 22 in guest to any unused port (8088 in my case) in host.
SSH is available in most Linux repository, and Windows can install it from Settings -> Apps -> Optional Features -> Add a feature -> OpenSSH Server.
By running SSH server in VM, host machine can run the command below to access it:
ssh -p 8088 jim@localhost
Replace port number 8088, and VM’s username jim to yours.
Or, use scp command to transfer files between host and VM. For example, send ‘Sigil-2.0.1.tar.gz’ package in host’s Downloads folder to VM user jim’s home directory:
