False recognized Vivaldi version
Vivaldi recognized her https://vivaldi.com/bugreport/ the version 1.94.966.3, although I installed the Version 1.13.966.3.x64 - s. screenshot. Is it a bug or a feature?
it had to be done because there are badly coded sites which think that 1.10 version was OLDER than 1.9 so all the newer versions than 1.9 had to fake a 1.91, 1.92 etc version.
Some bad sites do not know that Vivaldi versions can be greater than 1.1 and misdetect it.
Thats why the browser useragent is faked as Vivaldi 1.9x.
You can see the useragent by opening vivaldi://about
