Many Linux distributions include Firefox by default while most have a package management system - a preferred way to install Firefox. Package management system will:

  • Ensure that you have all the required libraries
  • Install Firefox optimally for your distribution
  • Create shortcuts to launch Firefox
  • Make Firefox available to all users of your computer
  • Make removing Firefox work the same as removing any other application

Package management system has downsides:

  • It may not give you the latest Firefox version
  • It may give you a version without Firefox branding

You can also install Firefox through the Flatpak option.

Visit Firefox Flathub page and click the button.


To install Firefox using the package manager, please refer to your Linux distribution's documentation.

The support sites for some Linux distributions have complete instructions on how to install Firefox without using a package manager, although a few information may be out of date. For example:

You can also follow the instructions below to manually install on each user's account.

  • Before you install Firefox, make sure that your computer has the required libraries installed. Missing libraries will cause Firefox to be inoperable.
  • The installation file provided by Mozilla in .tar.bz2 format has pre-compiled binary files as opposed to sources. There is no need to compile the program from the source: simply unpack and run the binaries.
  • The following instructions will install Firefox into your home directory. Only the current user will be able to run it.
  1. Download Firefox from the Firefox download page to your home directory.
  2. Open a Terminal and go to your home directory:
    cd ~
  3. Extract the contents of the downloaded file:
    tar xjf firefox-*.tar.bz2
  4. Close Firefox if it's open.
  5. To start Firefox, run the firefox script in the firefox folder:
    ~/firefox/firefox
    Firefox should now start. You can then create an icon on your desktop to run this command.
  6. There's no need to keep the installation file:
    rm firefox-*.tar.bz2

libstdc++5 error

As noted above, you need to install the required libraries for Firefox to work. Many distributions don't include libstdc++5 by default.

'firefox not installed' message or wrong version of Firefox starts

If Firefox is installed following the instructions given above, it must be started (in a Terminal or in a launcher on the Desktop, for example) using the command: ~/firefox/firefox

If you try to start Firefox in a Terminal with the command: firefox, it will either start the package-manager-installed version of Firefox or will tell you the program is not installed.

Introduction

Kali Linux is a Debian-derived Linux distribution designed for penetration testing. With over 600 preinstalled penetration-testing programs, it earned a reputation as one of the best-operating systems used for security testing. As a security-testing platform, it is best to install Kali as a VM on VirtualBox.

Kali has a rolling release model, ensuring up-to-date tools on your system. Also, there is an active community of users providing ongoing support.

This step by step tutorial shows you how to install Kali Linux on VirtualBox.

  • At least 20 GB of disk space
  • At least 1 GB of RAM (preferably 2) for i386 and amd64 architectures
  • VirtualBox (or alternative virtualization software)

Since these instructions take you through the installation process in a virtual environment, you need to ensure you have one set up on your system. In this article, we are using VirtualBox, as it is a simple to use, open-source virtualization solution.

In case you do not have VirtualBox installed, use this step-by-step VirtualBox installation guide.

On the official Kali Linux website downloads section, you can find Kali Linux .iso images. These images are uploaded every few months, providing the latest official releases.

Navigate to the Kali Linux Downloads page and find the packages available for download. Depending on the system you have, download the 64-Bit or 32-Bit version.

After downloading the .iso image, create a new virtual machine and import Kali as its OS.

1. Launch VirtualBox Manager and click the New icon.

2. Name and operating system. A pop-up window for creating a new VM appears. Specify a name and a destination folder. The Type and Version change automatically, based on the name you provide. Make sure the information matches the package you downloaded and click Next.

3. Memory size. Choose how much memory to allocate to the virtual machine and click Next. The default setting for Linux is 1024 MB. However, this varies depending on your individual needs.

4. Hard disk. The default option is to create a virtual hard disk for the new VM. Click Create to continue. Alternatively, you can use an existing virtual hard disk file or decide not to add one at all.

5. Hard disk file type. Stick to the default file type for the new virtual hard disk, VDI (VirtualBox Disk Image). Click Next to continue.

6. Storage on a physical hard disk. Decide between Dynamically allocated and Fixed size. The first choice allows the new hard disk to grow and fill up space dedicated to it. The second, fixed size, uses the maximum capacity from the start. Click Next.

7. File location and size. Specify the name and where you want to store the virtual hard disk. Choose the amount of file data the VM is allowed to store on the hard disk. We advise giving it at least 8 GB. Click Create to finish.

Now you created a new VM. The VM appears on the list in the VirtualBox Manager.

The next step is adjusting the default virtual machine settings.

1. Select a virtual machine and click the Settings icon. Make sure you marked the correct VM and that the right-hand side is displaying details for Kali Linux.

2. In the Kali Linux – Settings window, navigate to General > Advanced tab. Change the Shared Clipboard and Drag’n’Drop settings to Bidirectional. This feature allows you to copy and paste between the host and guest machine.

3. Go to System > Motherboard. Set the boot order to start from Optical, followed by Hard Disk. Uncheck Floppy as it is unnecessary.

4. Next, move to the Processor tab in the same window. Increase the number of processors to two (2) to enhance performance.

5. Finally, navigate to Storage settings. Add the downloaded Kali image to a storage device under Controller: IDE. Click the disk icon to search for the image. Once finished, close the Settings window.

6. Click the Start icon to begin installing Kali.

After you booted the installation menu by clicking Start, a new VM VirtualBox window appears with the Kali welcome screen.

Select the Graphical install option and go through the following installation steps for setting up Kali Linux in VirtualBox.Freecad review.

1. Select a language. Choose the default language for the system (which will also be the language used during the installation process).

2. Select your location. Find and select your country from the list (or choose “other”).

3. Configure the keyboard. Decide which keymap to use. In most cases, the best option is to select American English.

4. Configure the network. First, enter a hostname for the system and click Continue.

5. Next, create a domain name (the part of your internet address after your hostname). Domain names usually end in .com, .net, .edu, etc. Make sure you use the same domain name on all your machines.

6. Set up users and passwords. Create a strong root password for the system administrator account.

7. Configure the clock. Select your time zone from the available options.

8. Partition disks. Select how you would like to partition the hard disk. Unless you have a good reason to do it manually, go for the Guided –use entiredisk option.

9. Then, select which disk you want to use for partitioning. As you created a single virtual hard disk in Step 3: Adjust VM Settings, you do not have to worry about data loss. Select the only available option – SCSI3 (0,0,0) (sda) – 68.7 GB ATA VBOK HARDDISK (the details after the dash vary depending on your virtualization software).

10. Next, select the scheme for partitioning. If you are a new user, go for All files in one partition.

11. The wizard gives you an overview of the configured partitions. Continue by navigating to Finish partitioning and write changes to disk. Click Continue and confirm with Yes.

12. The wizard starts installing Kali. While the installation bar loads, additional configuration settings appear.

13. Configure the package manager. Select whether you want to use a network mirror and click Continue. Enter the HTTP proxy information if you are using one. Otherwise, leave the field blank and click Continue again.

14. Install the GRUB boot loader on a hard disk. Select Yes and Continue. Then, select a boot loader device to ensure the newly installed system is bootable.

15. Once you receive the message Installation is complete, click Continue to reboot your VM.

With this, you have successfully installed Kali Linux on VirtualBox. After rebooting, the Kali login screen appears. Type in a username (root) and password you entered in the previous steps.

Finally, the interface of Kali Linux appears on your screen.

With this guide, you have learned how to install Kali Linux in VirtualBox. We also covered setup and configuring to start penetration and security testing.
