So far so good (well almost) with ditching Chrome for Vivaldi webrowser. I ran into a situation where a couple of online logins do not work for me (yet) on Vivaldi.
Good news is that the Vivaldi browser can install Chrome extensions, including the proton password extenstion. Export from Chrome, import into Chrome and baddaboom (or is it ‘baddabing’?) I don’t need chrome or its passwords manager anymore (well not quite true yet, as I said a couple of hiccups.)
