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.sowith 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?
