Linux users have access to both NPAPI and PPAPI versions of Flash Player. However, for the last four years, the NPAPI version has been held at 11.2 and regularly updated with only security fixes while the PPAPI version (used in Chrome and Chromium based browsers), is in line with the standard Windows and Mac releases.
Adobe are updating the beta channel with Linux NPAPI Flash Player by moving it forward and in sync with the modern release branch (currently version 23). 
Now if you would like to use this Adobe Flash Player 23 on Fedora, please check the following steps:
# sudo cp libflashplayer.so /usr/lib64/flash-plugin/libflashplayer.so
