What "Report Diagnostics" do?
It reports what diagnostics to who?
Where do you see this? I presume that it's some kind of crash report, in which case the details of your setup would be sent to Vivaldi developers for analysis.
You can see it in the privacy-section in the settings-manager.
It would be really interesting to knowing about this. Can somebody tell us, what informations / diagnostics are inlude in this "feature"?
I'd like to know more about this too please.
