Besides, I had to replace libffmpeg.so becuase youtube said, my Opera didn't support h.264, so I downloaded opera-ffmpeg-codecs-58.0.3029.81-1-x8664.pkg.tar.xz from repo.herecura.eu/herecura/x8664/... and now everything is all right!
Thank you so much for pointing that out! I am finally able to play h.264 videos with opera on my fedora machine!

This box pops up when i try to unsubscribe to an address.
I cant post pictures off my computer to facebook.
And i think when i was trying to forward an email the other day this popped up.
Now my work around. Added Opera extension to 'Open in Chrome'. Simple to right click on video in question, select 'Open Link in Google Chrome'. This will satisfy me.
If netflix requires widevine (package chromium-widevine) and not the usual chromium-codecs-ffmpeg-* ones, you are out of luck since ubuntu does not package chromium-widevine at all.
Highlights
We fixed some UI issues on Linux: O-menu elements are more visible again and the menu is positioned correctly. Plus, the context menu does not have a black border anymore
Well, I have the same issue on opera stable. It seems that the light and dark built in themes only change the address bar and the tab bar and nothing more. Even the recently closed tabs menu uses the light theme!
Obviously, it is not related to the dark gtk theme bug. This was solved by forcing opera to use some gtk theme they have made (light grey menus, darker grey selected entries and black letters).
You can not do what you ask because, in general, you can not set a custom search engine as the default and thus have it appear on spped dial.
However, you can add youtube's search as a custom search engine. Right click on youtube's search field > create search engine > fill the details there > done.
