I can see this show up on Youtube (why not - under Google's control, and they want you to watch the ads on their official browser) and on banking apps. Initially. In the longer run, it either withers and dies, or it leads to antitrust action. I really can't see another way.
It rejects Firefox and Chrome outright. The solution is to use either browser on Wine, then copy the session cookies over.
Last I tried was over a month ago... I will give it another go soon. I do not expect progress.
