The first question I would ask if you get your account hacked or your Id stolen is.
Which browser did you use?
Yes, I am from Norway and Opera is my favourite browser regarding security. Vivaldi is a true son of Opera, but I don't know that browser well enough to conclude on its security. Probably it is at least as secure as Opera, but I don't know.
There is as far as I know no browser that has a better data solution (data tab / data history) than Vivaldi. So if you got your Id stolen while you surfed the web with Vivaldi, you should at least be able to analyze what happened.
What is the most secure browser?
