This question already has an answer here:

I use the version of Iceweasel on Debian Stretch GNU/Linux on an x86_64 machine. Sadly, I need to use Adobe's abominable Flash technology.

I know that the way you install the Flash plugin on Debian is using the flashplugin-nonfree package, after making setting the appropriate APT source settings. Well, I have, and it's installed and up-to-date - as far as the package goes, but, woe is me, when I open sites with Flash in Firefox it tells me that my Flash player is out-of-date!

So, first question:

  • Is this my fault somehow (e.g. misconfiguration or what not), or is it just that the Stretch package maintainers haven't updated their version?

And then:

  • Should I manually install the up-to-date plugin from adobe.com, or is there some other Debian-ish alternative?
  • If the answer to the previous question is "yes", then - should I just overwrite /usr/lib/flashplugin-nonfree/libflashplayer.so with the downloaded version, and overwrite the local settings, like Adobe's .tar.gz's README suggests, or should I do something else and Debian-specific?

  • What browser are you using? I use pepperflashplugin-nonfree with Chromium. – Faheem Mitha Feb 2 '16 at 18:13
  • @FaheemMitha: Iceweasel, see edit. But thanks. – einpoklum Feb 2 '16 at 18:23
  • Maybe check for alternatives with Iceweasel. Though perhaps there aren't any. – Faheem Mitha Feb 2 '16 at 18:26
  • Or give wiki.debian.org/Freshplayerplugin a try. – Faheem Mitha Feb 2 '16 at 18:32

You can update the Flash plugin using

sudo update-flashplugin-nonfree

which is provided by flashplugin-nonfree.

Alternatively you can use Chrome's Flash plugin in Iceweasel using the browser-plugin-freshplayer-pepperflash package (and pepperflashplugin-nonfree).

  • Stephen, either great minds think alike, or you swiped my research. :-) – Faheem Mitha Feb 2 '16 at 18:34
  • @FaheemMitha I know, I saw your comment after I finished researching my edit! – Stephen Kitt Feb 2 '16 at 18:35
