Problem playing online videos on Ubuntu 16.04 [duplicate]

I have the latest, Ubuntu 16.04, with the latest Firefox and Adobe Flashplayer version 11. Videos from YouTube, Vimeo, etc. are working fine. But no video from Star Sports will play. Why is this and how can I fix it?

The old way of installing Adobe Flash with sudo apt-get install flashplugin-installer is no longer supported. Instead, you need to use Fresh Player.

To Install

As of 16.04, Fresh Player is available in the official repositories. Installing is as simple as:

 sudo apt-get install browser-plugin-freshplayer-pepperflash

However, if you still want the most up-to-date version, you can add the PPA:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install browser-plugin-freshplayer-pepperflash

This will install the actual player, but it still needs an extra file. This file is the actual pepperflash library used by the player. To get it, you can use a PPA:

sudo add-apt-repository ppa:skunk/pepper-flash
sudo apt-get update
sudo apt-get install pepflashplugin-installer

Close your browser and re-open, and it should be enabled. The reason Youtube and Vimeo worked most likely was because of the support of HTML5 video on those websites.
