@zalex108 No joy. I made the edits but they're overwritten upon re-opening the browser. Google wins again. Surprise, surprise

@zalex108 Thanks. I'll try it.

@zalex108 Are you in the US? I browsed to opera://cast/#devices and got a "This site can't be reached" error. Sadly, that's consistent with the fact that the Search box in Preferences returns nothing when I search for Chromecast :<

@leocg As the moderator of this forum, do you work for Opera? If so, can you find out and give a definitive answer about whether or not Chromecast is supported by Opera 50.0 in the US? It seems really poor form to advertise it as supporting Chromecast if that's not true for a big piece of the user base...

How about in the United States?

I'm on MacOS 10.13.2 and removed Opera fully, including all references in /Library/... and ~/Library/... I then did a fresh install and it's still the case that there is no Opera setting under Preferences - Browser - User interface that has anything to do with Chromecast, even though http://blogs.opera.com/desktop/2018/01/opera-50-introduces-anti-bitcoin-mining-tool/ says it's part of the new, production release. What gives?! I would love to ditch Chrome for Opera but can't without Chromecast support :<
