Flash plugin for Firefox on Ubuntu 16.04 [duplicate]

The flash player plugin has stopped working in Firefox on Ubuntu 16.04 .I cant find pepper flash for chromium either ,certain music sites require flash so are now not use-able.

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

This command got flash working in Firefox for me.

Go to Official Adobe flash website, then download the install_flash_player_11_linux.x86_64.tar.gz and extract the tarball using:

tar -zxvf install_flash_player_11_linux.x86_64.tar.gz

You got the libflashplayer.so. Now copy this file to /usr/lib/firefox-addons/plugins directory using:

sudo cp libflashplayer.so /usr/lib/firefox-addons/plugins
