Adobe Flash is proprietary software and hence Fedora does not include it by default

Flash plugin

You have to chose either based on the hardware architecture you are using.

x86_64 (64-bit)

su -c 'yum -y install http://linuxdownload.adobe.com/adobe-release/adobe-release-x86_64-1.0-1.noarch.rpm'
x86 (32-bit)

su -c 'yum -y install http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm'
Installing the plugin

su
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
yum -y install flash-plugin 
exit
Checking the plugin in Firefox

Type the following text in the Firefox address bar:

about:plugins
Also check the Adobe Flash Player test page

Installing the plugin on Chromium web browser

Follow all of the instructions in the Enabling Flash Plugin section. Then:

On 64-bit, create a symbolic link that tells Chromium how to find the 64-bit plugin:

su
ln -s /usr/lib64/mozilla/plugins/libflashplayer.so /usr/lib64/chromium-browser/plugins/libflashplayer.so
exit
On 32-bit, create a symbolic link that tells Chromium how to find the 32-bit plugin:

su
ln -s /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/chromium-browser/plugins/libflashplayer.so
exit
Exit all Chromium windows and restart Chromium. In the Chromium address bar, type "about:plugins" to check whether the plugin loaded. You may have to re-run Chromium with the --enable-plugins command line switch to force Chromium to re-scan its plugins folder.

DRM Flash Video support

Installing Gnash

There is a free and open source alternative called Gnash available in Fedora's software repositories. Gnash can play flash videos but the audio portion of flash is often under the MP3 format which is patent encumbered. Since Gnash uses Gstreamer, you can install the gstreamer codecs from RPM Fusion

su
yum -y install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

yum -y install gstreamer{1,}-{ffmpeg,libav,plugins-{good,ugly,bad{,-free,-nonfree}}} ffmpeg 
exit
Gnash is very modular and includes plugins for Mozilla and Konqueror as well as a desktop player. You likely want the Mozilla plugin.

su
yum -y remove nspluginwrapper 
yum -y install gnash-plugin 
exit
If you use Konqueror as your web browser,

su -c 'yum -y install gnash-klash'
If you would like to have a desktop flash player,

su -c 'yum -y install gnash'
