Firefox is Google's child. When Google cuts financing, it will die. /s

Firefox, since about 10 years, copies every crap that Chrome implements: UI - check, user hostility - check, frequent updates - check, poor security - check.

The point is that the "Log in with Google" notifications aren't in the browser code they're in the website code.
