Flash player not work in Last opera stable and developer
Flash player not work in Opera browser. In chromium all ok. I Use Ubuntu 16.04 with install adobe-flashplugin and pepperflashplugin-nonfree
I do not have an answer to your question, since here on debian testing opera works as it should on flash content, but I would like to mention that adobe-flashplugin includes both the npapi and ppapi versions of flash while pepperflashplugin-nonfree is a script that downloads and installs the ppapi version.
I would keep only one of them installed...
In the places listed in /usr/lib/x86_64-linux-gnu/opera/resources/pepper_flash_config.json.
Due to some personal problems this week, I do not have the time to search and troubleshoot the flash problem on opera 49. I will when I can, because I also get the
Sorry, Flash Player is either not installed or not enabled.
message on adobe's page. My pepper flash however is on /usr/lib/adobe-flashplugin/libpepflashplayer.so so opera probaly identifies it, but for some strange reason it does not use it.
Up to my count, this is now the eighteenth case report concerning the compatibility issues with Flash and Opera. There has been introduced a late resolution attempt by @natasha-from-dnepropetrovsk at the aforementioned link. I hope that works out for you folks!
