Same here. Surprised so many people have commented on this without questioning the veracity of the claim. Specifically, the claim that it is importing your firefox data without you giving it permission.
It's not that I have trouble believing this. It's definitely something they might do. But when did some random redditor become a reliable source?
For what it's worth, I just updated my Windows 10 install and all that changed was a new Edge icon appearing on the desktop, that's it. When I clicked it I had the option to load settings from Firefox which I declined. It didn't set itself as the default browser (maybe there was a prompt about it but I don't remember), but it did get pinned to the taskbar, which I now removed.
