Adobe Flash Player no longer distributed by openSUSE
Installation from Adobe repository
Adobe is providing an RPM repository which is compatible with openSUSE and SUSE Linux Enterprise.
To enable this repository on your system, in a terminal, run (you will be prompted for root password):
sudo zypper ar --check --refresh http://linuxdownload.adobe.com/linux/x86_64/ adobe
This adds the repository. Now use
sudo zypper se -s -r adobe
to see the packages provided by this repo. There are two packages: the flash plugin itself and a package named adobe-release-x86_64. It is recommended that you first install this additional package and add the repo's key then:
sudo zypper in adobe-release-x86_64 sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
Then, to install Adobe Flash Player rpm package, run:
zypper in flash-plugin
You'll need to restart Mozilla Firefox browser to make it detect Flash plugin.
