All of a sudden I have 2 gmail envelopes in the menu bar. Both open windows to log into Google. When I log in there I get just a small plain white window??? To get to my Gmail account I have to go to the Internet, enter Gmail.com, and then my log in information, and only then will I get to my email....I am using the latest version of firefox and just recently upgraded to Mojave. What am I doing Wrong? Any help appreciated!
