Adobe Flash Player 23 Beta Released. Install Adobe Flash 23 Beta for Firefox on Ubuntu 16.04. Linux users have access to both NPAPI and PPAPI versions of Flash Player.
The release statmenet by Adobe says that currently they are distributing 32 and 64 bit binaries only, but very soon they will package these in proper installers after additional testing and feedback. Users should manually back-up their existing Flash Player plugin file from the appropriate system plug-in folder and copy the new binaries into place to use them. Please note that our initial release does not support Fedora based distributions. Users who require this functionality are recommended to use Pepper (PPAPI) Flash for Linux.
