Since last Saturday (October 20, 2018), I have not been able to log in to Garmin Connect using the Firefox browser. When I click on the "Sign in" icon, the page that comes up does not contain the box where Username and Password are entered.
I am posting this from the Chrome browser, because when I opened Garmin Forums with Firefox, I wasn't allowed to Login. The Login option was grayed out.
Was an update made to Garmin Connect in the past week? If so, did you test it against Firefox?
