2] finally open "gmServiceGmail.js" with notepad

3] edit those 2 lines below:

loginURL = "https://www.google.com/accounts/ServiceLoginAuth";

should be changed to:

loginURL = "https://accounts.google.com/accounts/ServiceLoginAuth?service=mail";

and:

loginURL = "https://www.google.com/a/" + this.domain + "/LoginAction2";

should be changed to:

loginURL = "https://accounts.google.com/a/"+ar[1]+"/LoginAction2?service=mail";

4] save "gmServiceGmail.js" restart FireFox and your Gmail manager accounts should be working correctly.

I have made this change to 6 XP computers so far each have 4 gmail accounts and they all function correctly.

Thanks once again to divrsit for posting this fix.
