Freshplayer Flash Plugin

You might or might not be aware that Adobe is no longer developing Flash for Linux. Google Chrome comes with its own version of flash player, so that is not a concern. However, for Firefox users, the only way to get the most current version of flash player is by using Chrome’s Pepper Flash plugin. For the longest time, this has been a source of frustration. A lot of people have been worried about being left behind on an old version of flash. No longer is this a problem. A developer has created a plugin wrapper for Firefox (it will not work with other browsers).

Before Freshplayer can be installed, Pepper Flash needs to be. Open a terminal window and enter the following commands.

sudo apt-get install pepperflashplugin-nonfree

Once installed, configure it

sudo update-pepperflashplugin-nonfree --install

Now that Pepper Flash is installed, it’s time to install the Freshplayer wrapper

sudo add-apt-repository ppa:nilarimogard/webupd8

After adding the PPA, update your software sources and install the Freshplayer plugin

sudo apt-get update sudo apt-get install freshplayerplugin
