Thank you.

After following the discussion here:
https://forums.opera.com/topic/19182/opera-browser-does-not-play-twitter-videos-and-gifs-again/17
...and trying the suggestions, still not working.

Had to go here:
https://get.geo.opera.com/pub/opera/desktop/
...and install previous stable version, which works just fine.

Opera is my preferred browser, but these ongoing issues with video/streaming/flash is just getting out of hand...

Once again streaming flash is no longer working properly after latest update.
Youtube works fine, but streaming no longer working. Here are a few examples:

Previously had it working by using:
mkdir /usr/lib/PepperFlash
cp libpepflashplayer.so /usr/lib/PepperFlash/

...but now, nothing...
Works fine with Firefox - getting frustrated with this seemingly ongoing problem with Opera.
Any help is much appreciated.
