Youtube uses the HTML5 player whenever possible and only fall back to Flash Player if need to. https://www.youtube.com/html5/

The latest version of the NPAPI Flash Player Plugin for Linux from Adobe is 11.2.202.632

However many sites (news sites for example) are dropping support for the supported NPAPI Flash Player 11.2 branch used on Linux and the older discontinued 11.1 branch used by Android and BlackBerry PlayBook.

About the only way to use a current branch version of Flash Player is to use say the Freshplayerplugin wrapper to make use of the Pepper Flash from say Chromium.

I have not tested the freshplayerplugin wrapper for a year now and do not use Ubuntu Linux distros to suggest how to get this set up. But it did work pretty well when I did use it.

While the info provided didn't solve the issue it certainly was informative. I think the issue is that Adobe quit supporting the Linux platform. Now if anybody can lead this poor user to the solution suggested, I would be most grateful. it is the last function to completely rid myself of Windows.

Adobe still supports Linux as I said, just that they only do so with security updates for the NPAPI Flash Player 11.2 branch as 11.2.202.632 was released when there were Flash Player updates for Windows and Mac.

As said the only way to perhaps have a more current branch of Flash Player which is the PPAPI Pepper Flash 22.0.0.209. Firefox does not support the PPAPI Pepper Flash on any OS however it is possible by the Freshplayer wrapper plugin on Linux.

Thanks for the reply. I tried using the steps on the following site: http://www.webupd8.org/2014/05/install-fresh-player-plugin-in-ubuntu.html It all seems to have loaded correctly. Google Chrome downloaded & installed. I rebooted the system & tried Xfinity again; but had the same results. Is there something I missed?

Actually we may have a better option now.

A easy way to use this is to place the libflashplayer.so file in a created plugins folder at ~/.mozilla/plugins/

I have not tried the Freshplayer wrapper plugin in a year to know if it still works good or not but at least Linux users had a option to try.

This may not be needed now as Adobe has done a u-turn on NPAPI Flash Player support on Linux as per above..

Thanks James, Followed the advice above, got the .so file downloaded. This is where my novice Ubuntu knowledge comes into play. For the life of me I couldn't find the subdir: /mozilla/plugins. I even tried using Double Commander. Firefox came embedded w/Ubuntu I'm not sure if that's why. I am waiting on a couple of books from the library: Ubuntu for Dummies and a much deeper look with Ubuntu Unleashed. Back to school I guess. Anyway thanks greatly for your time & help. If you don't do this for a living you missed your calling. Did IT support for many years you'd fit right in. Pat

Make sure you can view hidden folders/files in a filemanager. The .mozilla is in /home/username/.mozilla and just create a plugins folder there. Then place the Plugins like the libflashplayer.so file in folder.

If Firefox is still running when you do this then you can type about:plugins in Location (address) bar or restart Firefox for it to see this Flash Player Plugins. Also may need to deactivate the older Flash Player 11.2.x Plugin on Addons manager if still on system and in use by Firefox.

Thank James for working with me through this issue. It figures just after I got things setup & functioning did a software upgrade and the Flashplayer was part of the upgrade. The exercise you helped with was useful as a tutorial in learning a new environment. Still going to read on the op sys, there's a lot to learn. Thanks again, Pat
