Note that it doesn’t prevent sso sharing. I was signed into Amazon and a separate Firefox (actually librewolf) tab I had opened looking up a movie star on… IMDb force created an account for me using my Amazon account. No I did not get a prompt to accept it and no I did not click anywhere near the login buttons. Seen that this has happened to a few people but not everyone so it’s almost like they’re slow rolling it.

I’ve since isolated Amazon into its own profile altogether and added Amazon to unlock on my main browser profile. And of course requested deletion of my sudden imdb account
