Flash Player is a necessary part of Firefox. It allows you to play videos and other multimedia content on your computer. If you don’t have Flash Player, you can install it from the Mozilla Firefox web browser’s installation page. To install Flash Player in Firefox on Ubuntu Hardy, follow these steps:

  1. Open the Ubuntu Hardy Terminal window and type the following command to start the installation process: sudo apt-get update sudo apt-get install flashplayer

The issue is some underlying error in Ubuntu Gutsy with package management… and the solution is to install Flash Player 9 directly via the Adobe website.

Installing Without Command Line

Yes, you can install this without troubling yourself to open the command line at all. (Command line instructions are below).

Right-click on the downloaded installation file and choose “Extract Here” from the menu.

Now open up the new folder and double-click on flashplayer-installer. When prompted, choose to “Run in Terminal”

You’ll have to click inside the window and hit the Enter key and then the y key at the prompts. (Make sure you have Firefox closed)

Now your Flash player should be working just fine.

Installing from the Command Line

If you prefer to install from the command line, you can run the following commands to download and install flash player. Make sure you’ve closed all instances of Firefox before you start this.

Verifying Installation

tar xvfz install_flash_player_9_linux

cd install_flash_player_9_linux

./flashplayer-installer

Type about:plugins into the address bar, and verify that you see Shockwave Flash in the list.

That should be all you need to do.
