How do i get rid of the Google Login Window
 

Fedora-38-KDE , How do I get rid of the Google Logins.
I'm having problems changing passwords.

I'm guessing on this since I don't have a way to reproduce the issue

But try going to System Settings and see if there's a listing for "Online Accounts" (Likely within the Personalization category)

You might be able to resolve the issue there

Could you provide more detail and perhaps post a screenshot?

I've encountered numerous annoying Google login dialogs, but generally just on websites. And, no, I wouldn't use one on a bet.

The dialog to attach a file appears when you click the "Go Advanced" button under the compose/edit post window.

This is where it is in firefox 120
or navigate the menu to "settings", select "privacy & security".

from here you may remove passwords for selected websites, etc.

I hope this helps.

I'm thinking the solution posted above by @GlennsPref is what you're looking for..

At the time, I was thinking this was a desktop "notification pop-up" issue I didn't realize you were talking about websites
