To install Adobe Flash Player on a Fedora Linux 19 or 20 system, you can follow these steps:
Download the Adobe Flash Player installer from the Adobe website. Make sure to select the correct version for your system (32-bit or 64-bit).
Open a terminal and navigate to the directory where you downloaded the installer. For example:
cd /path/to/downloads
chmod +x install_flash_player_32_linux.x86_64.rpm
sudo rpm -ivh install_flash_player_32_linux.x86_64.rpm
Keep in mind that Adobe Flash Player is not a natively supported plugin on Fedora Linux, and it may not work properly on all websites. If you encounter any problems or have any questions, it may be helpful to seek out resources or assistance online or from the Fedora community.
Note: Adobe Flash Player is being phased out and is no longer supported by Adobe. It is recommended to use alternative technologies such as HTML5 for web content.
