Glad to see it was the plugin causing the looping issue, have downloaded 0.5.7.1 and can log in now!

This review is for a previous version of the add-on (0.5.7.1). 

Actually it wasn\'t the extension causing the looping issue but it\'s now preventing it. The issue was that when Gmail was trying to login to your account it was throwing it in an endless loop because of the cookies.\r\n\r\n- TL
