@leocg Generally I'm pretty impressed with Opera One on macOS 14.4.1. Its worlds away, as I guess we should expect, from the first time I tried it back in 2017.
Unfortunately it will still need to go a little further with security features as it currently does not block "fingerprinting" as some others like Brave browser does.
In all other respects I'm liking it more and more.
The Aria AI is cool, I was surprised when I highlighted some text in Indonesian to get a popup notification offering to translate to English by Aria amongst other options like "look up" and more.
Basically it's easy to setup and use and easy on the eye.
It's system resource use is fairly low although not as low as some.
I would consider it as a default browser if the fingerprinting issue was addressed in Security and Privacy settings.
