Since there is currently some discussion about Chrome/Chromium security
concerns, is Vivaldi (based on Chromium code I understand) also affected
with the same security issues?

If no one knows, what procedure do I go through to determine the answer
myself (with the understanding that I am basically a computer idiot, but
I quit Windows entirely in 2004 and became an Ubuntu user until earlier
this year when I jumped on to Devuan).
