Open Source: No, but I'm pretty sure it is allowed to be packaged like the NPAPI one
Tarball: https://fpdownload.adobe.com/pub/flashplayer/pdc/23.0.0.207/flash_player_ppapi_linux.x86_64.tar.gz
This is especially useful now that Vivaldi has made it into the unstable repos!
Adobe-flash player files is not founded in/with the opera-stable package, therefor i installed at its files manually, the reference it is this.
