So, i don't really like to use Google Chrome / Chromium. Although flash is dieing some websites such as twitch have yet to make the move to HTML 5. I'd highly advise turning on click to play. Using the freshplayer wrapper we can use Chrome's flash player on Firefox and Firefox based browsers. The reason being that Adobe's flash is outdated. For Ubuntu 16.04 and 15.10 Code: sudo apt-get install pepperflashplugin-nonfree browser-plugin-freshplayer-pepperflash This should also work on Debian Jessie provided you enable the nonfree and contrib repositories. For Ubuntu 14.04 Code: sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install browser-plugin-freshplayer-pepperflash Note: You should probably uninstall any other flash player's to avoid conflict.
