I am using the latest flashplayer I can find for Ubuntu 16.

I only get this error (process:9281): GLib-CRITICAL **: g_path_get_basename: assertion 'file_name != NULL' failed

I tried starting Firefox in safe mode.

It works when I restart the computer completely, but then after some time playing videos, it fails on me. It stops playing altogether, and when I click on a new video, even after killall firefox and restarting firefox, it only shows one or two frames from the video and won't progress at all.

I'm really not sure how to debug this at all. Thanks in advance.

Some updates:

 firefox

I suspect this is a problem with freshplayer wrapping pepperflash.

  • I don't understand the question. What do you mean by "system's configuration"?

  • I don't see what that has to do with it. AMD Athlon X4, Asus Radeon R9 270X, Gigabyte GA-F2A88X-D3H ATX FM2+

  • I can suggest you try a live CD and see if everything works. If it does, reinstall.

The follow appears to have worked for me:

Can I use Chrome's Pepper Flash with Firefox?

sudo aptitude --purge-unused purge flashplugin-installer adobe-flashplugin adobe-flash-properties-gtk adobe-flash-properties-kde browser-plugin-freshplayer-pepperflash

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install pepperflashplugin-nonfree
sudo update-pepperflashplugin-nonfree --install
