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
