On a fresh installation of 16.04 Firefox will not stream audio from msnbc.com/listen
I tried this:
sudo apt update && sudo apt full-upgrade
sudo apt install flashplugin-installer
sudo apt install adobe-flashplugin
I found a solution in the comments at this link.
Link to a solution to this problem.
I am looking for a better solution that can be implemented more quickly. I tried the solution (which involves re-installing Ubuntu) but it did not solve the problem.
The following was also tried.
sudo apt remove flashplugin-installer
sudo apt purge flashplugin-installer
sudo apt remove adobe-flashplugin
sudo apt purge adobe-flashplugin
sudo apt remove firefox
sudo apt purge firefox
sudo apt install firefox
Notes: The Opera browser has no problem with that audio source. Youtube audio also works. Note that Adobe Flash or Shockwave Flash are actually not even necessary in Firefox. I have another 16.04 computer with the Shockwave Flash (plugin for Firefox) disabled and yet audio will stream.
