Amazon instant video 14.04.1 LTS [duplicate]

I have recently installed Ubuntu 14.04.1 LTS and I am having trouble using Amazon Instant Video. When I click on a video to play there is no option to play it, it just says that I can play it on a compatible device (kindle, phone,...) is there some package or something that I need to install?

Thanks for any help

I have successfully (I think) implemented the solution below but I still have the same problem.

After following the below I get:

nathan@nathan-S400CA:~$ sudo mkdir /etc/hal/fdi/preprobe   
[sudo] password for nathan:     
mkdir: cannot create directory ‘/etc/hal/fdi/preprobe’: File exists    
nathan@nathan-S400CA:~$ sudo mkdir /etc/hal/fdi/information    
mkdir: cannot create directory ‘/etc/hal/fdi/information’: File exists    
nathan@nathan-S400CA:~$ /usr/sbin/hald --daemon=yes --verbose=yes

nathan@nathan-S400CA:~$ rm -rf ~/.adobe

You need this flash plug in

sudo add-apt-repository ppa:mjblenner/ppa-hal
sudo apt-get update 
sudo apt-get install hal

Here is a post with more information LINK Post number 3

If after a reboot it wont work then copy paste this to a terminal, ONE LINE AT A TIME

sudo mkdir /etc/hal/fdi/preprobe
sudo add-apt-repository ppa:pipelight/stable
sudo apt-get update
sudo apt-get install --install-recommends pipelight-multi
sudo pipelight-plugin --update
sudo mkdir /etc/hal/fdi/information

/usr/sbin/hald --daemon=yes --verbose=yes

rm -rf ~/.adobe

Do not be worried by these commands enter them one at a time and tell me of any errors ,reboot when you are finished.

OK If this is not working for you we will try another way, open terminal run one at a time

sudo add-apt-repository ppa:pipelight/stable
sudo apt-get update
sudo apt-get install --install-recommends pipelight-multi
sudo pipelight-plugin --update

If a Microsoft core fonts licence screen comes up, first perss the tab key and then enter.

next run this command (this undoes what we first tried)

sudo apt-get remove --purge hal

And finally

sudo pipelight-plugin --enable flash

You could reboot here don't think you need to up to you.

Open your web browser and go to your video, the browser shoud automaticly try to download a plug in, give it permission if you have to.

When it is installed close your browser then open it again and it should work

To get silverlight close the browser

sudo pipelight-plugin --enable silverlight

Open the browser go to the video and the plug in will install then restart the browser.
