Windows 10: Turned Off 'Sign-In With Google' Pop-ups

Disable Google Sign-in pop up

Windows 10. Every time I open Google.com (my home page in my FireFox browser) the Google sign-in pop up appears. I have disabled "Google Account Sign-In Prompts" in Firefox but the problem persists. How can I stop this annoying pop up?

 

Google Sign In Pop Up

No changes made to my system recently, but all of a sudden I'm getting a Google Sign In Pop Up.

First pop up box: Sign in with your Google Account (username), which takes you to a similar box for Password, which if entered takes you to a box with a weird choice, something along the lines of "Microsoft Apps want to delete all your Gmail."

Outlook has been and continues to access gmail normally. Any ideas what this is? Lots of internet hits on this pop up, but it always is linked to the Chrome Browser. I do not have Chrome installed on this Windows PC.

 

Before you continue to Google - new Google sign in?

First thing I get after launching Edge is a Google pop-up "Before you continue to Google". Problem: a. I may set cookies preferences as many times as I want, they are -not- saved b. when I use the [Sign in] button within the pop-up, or, after setting cookies preferences (pop-up disappears) sign in the normal way when relaunching Edge, this "Before you continue to Google" shows up again. Any suggestions? Thanks!
