Most videos are playing; some aren't
1 Attachment(s)
Running Xubuntu 16.04LTS on a 64 bit Dell Optiplex GX 520. The browser is Firefox 53.0.(64-bit) All Youtube videos play all right but on some other websites I get this message when I click on the play arrow. (screenshot) Any idea what I need to do? Thanks.

You would need the freshplayerplugin for firefox and the PPAPI version of flash. By the looks of that error. Not a default for most distro setups. But doable.

hydrurga 04-28-2017 03:50 AM

Can you give the URL of a sample site/video?

Also, what is the output from dpkg -l '*flash*' ?

you got a image of search paths that firefox uses to look for a flash plugin, get a pepper flash create one of them search paths then move that file into it. fixed.


just put it in

for local use only.
That is where I have mine, but I too have done this the other way as well, both ways always works for me.

That one above, I got out of a deb file using ark to untar it.


I just checked my page and its outdated
I just downloaded another one from that sight putting it in to the same home dir

even though it looks like this one
is chugging right through them because I am not having any issues with watching Youtube videos with being outdated already.

I agree with BW-userx - you're just missing the pepperflash plugin that Firefox is expecting. I use neither Ubuntu nor Firefox, but pepperflash is a common requirement.

You can start with


sudo updatedb
Let it finish

then do


locate libpepflashplayer
To see if you got it or not.

rokytnji 04-28-2017 12:41 PM

For BW-X post.


locate libflashplayer
should suffice.

then just do this to update it too.

userx%slackwhere ⚡ ~ ⚡> locate libflashplayer

# copy or move new one over top old outdated one.

userx%slackwhere ⚡ ~ ⚡> sudo cp -v /home/userx/.mozilla/plugins/ /usr/lib64/mozilla/plugins/
'/home/userx/.mozilla/plugins/' -> '/usr/lib64/mozilla/plugins/'

FreshPlayerPluin is a translation layer for NPAPI to PPAPI calls. That plus the pepperflash plugin works for most modern things. But still a manual process for many distros, so that means security updates are also manual. And flash tends to update at least monthly if not weekly for security updates. The NPAPI to PPAPI layer ensures that legacy games and other things still work. While presenting a modern / windows-ish version number that doesn't get you blocked by many sites these days.

For my setup:




Where is from source:
$ git clone

Where and manifest.json are from the .tar.gz.
Click need Flash Player for another computer.
Step 1 to Linux (64 bit)
Step 2 to (PPAPI) and .tar.gz

Where freshwrapper.conf tells the plugin to look at $HOME/.mozilla/flash/ for the PPAPI plugin.

pepperflash_path = "/home/iceweasel/.mozilla/flash/"
Plus the other default bits in the example from the source tree of freshplayerplugin.

Just launch synaptic and do a search for pepperflash. Select the resulting packages and install them.

Thanks guys. I'm a little uncertain about all the suggested commands though, especially since (per Awesome's advice) I looked in Synaptic and it seems I already have pepper flash (screenshot). Is this the case or do I need to run those suggested searches and commands?

AwesomeMachine 04-29-2017 02:43 AM

Pepperflash gets its actual flash plugin from the Chrome browser. If Chrome is not installed, pepper flash won't work. So, you should uninstall the pepperflash packages, install the Chrome browser, and reinstall the pepperflash packages. Then you should have HTML5 capability in firefox, which is what you want.

there's 2 packages.
one of them has a green square, the other an empty square.
what does that tell you?

on a sidenote...
many people are not making full use of the synaptic search function.
if you just enter the text in the little text field, you only get packages that have the exact string enetered in their name.
if, however, you press the magnifying glass you get more options, e.g. "look in description and name".

Ok, I'm going to go against the grain here, Gregg. If you're not using Chrome then you don't need Pepper Flash (at least for the moment as Firefox still supports NPAPI flash). In fact, because you have a residual configuration of pepperflashplugin-nonfree as well as an installed browser-plugin-freshplayer-pepperflash, things are not going to go smoothly as it is.

So, what I would suggest is that you close your browser and remove both peppers:

sudo apt-get --purge autoremove pepperflashplugin-nonfree browser-plugin-freshplayer-pepperflash

Then, reinstall flashplugin-installer just in case:

sudo apt-get --reinstall install flashplugin-installer

Then relaunch Firefox and test out the relevant videos again (the grammar one you posted works fine for me with Firefox and flashplugin-installer).
