Comment # 2 on bug 965537 from Andreas Stieger

Starting with openSUSE Leap 42.1, openSUSE no longer ships the Adobe Flash
Player. Most users will want to discontinue it's use anyway. Users can still
make use of the chromium-pepper-flash package (firefox users will also need to
install the freshplayerplugin package) which may be available in a community
repository like packman. You may also enable the "Adobe Flash" community
repository in YaST if you require legacy flash.
