Not totally comfortable with Firefox/Authy yet but need to be - I installed FF on my desktop - I added 5 profiles in addition to default and everything went great - Then I loaded FF on my laptop and iPhone and tried to sync and the "Sign in" popup appeared - I added Authy after the fact to get the "The Code" but that failed - Not sure what to do other than walk away from my initial install - I successfully setup a second install via a different email/password - Any thoughts w/b most appreciated, Thanks Dave
