Updating my Ubuntu version 13.10 to the 14.04 I've had to do the typical adjustments in the settings, and install some software packages that update has been removed.
One of them has been the flash plugin to display videos and other content in your web browser. The problem has been that the videos were very fast and no sound both with free such as the adobe flash plugin.
The solution has been to use the pepper flash plugin for Chrome, that has solved the problem both Mozilla Firefox and Chromium. To install it you must enter the two following commands in terminal
sudo apt-get install pepperflashplugin-nonfree
sudo update-pepperflashplugin-nonfree --install
And after a reboot we can already enjoy the Flash plugin and See videos on Youtube.
