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:

I suspect this is a problem with freshplayer wrapping pepperflash.
