I'm enjoying Vivaldi except I'm getting teapot & dead bird blank pages when opening Yahoo News links. They open ok but within a minute or two I get the blank page with what looks like a folded postage stamp of a dead bird or teapot. I've tried a lot of things to solve this, but no soap. So I want to see if I can use Chromium (not Chrome) full time. I need a way to transfer my complete Vivaldi profile to Chromium. Also since afaik Chromium is portable not installable I need to know how to transfer my profile to newer Chromium versions. Even how to transfer the new updated profile back to Vivaldi if I so choose. I did search but all I found was how to transfer TO Vivaldi when I want to tranfer from Vivaldi. And it was just about bookmarks not whole profiles.
