Lately I'm getting a pop-up on my laptop and iphone offering to log in via my Google account. I don't have a Google account, and all the help articles I find just tell people how to disable that. I have cookies set to Strict, I've cleared the cache, made sure things are updated, and I still get this annoying pop-up. I've got various add-ons installed. AdGuard, ClearURLS, Cookie Autodelete, Decentraleyes, UBlock Origin, Disable HTML5, Facebook Container, Flash Control, and HTTPS Everywhere. I'm open to suggestions on where to go from here. Frustrating for this to just start suddenly, and having to find a way to disable it.
