Support for TLSv1.2 and 256-bit forward secrecy cipher suites
It would be very nice if Vivaldi supported strongest TLSv1.2 cipher suites that are currently disabled in Chrome: - ECDHE-RSA-AES256-GCM-SHA384, - DHE-RSA-AES256-GCM-SHA384, - ECDHE-RSA-AES256-SHA384, - DHE-RSA-AES256-SHA256. So the browser could connect to servers supporting only 256-bit grade security like [url=https://thundr.eu/]thundr.eu[/url] (Qualys report [url=https://www.ssllabs.com/ssltest/analyze.html?d=thundr.eu&hideResults=on]here[/url]).
If this is a request for the browser, sorry but you put it in the wrong forum.
You want the Vivaldi browser section for all platforms https://vivaldi.net/forum/all
Already in Vivaldi.
