When I tried to synchronize my password on app it came back unrecognized? In the end I tried reset password it sent e a link to my email account it didn't recognize? So I followed link and changed password? I used said combo? Once all was finished I returned to synchronization of app new password working I set all up banking, a loan and social media once done I remembered email when it came to password it came back un-recognized?? I thought hey how I'd just set up around 5 accounts needing new password? So I logged out of Firefox & back into gmail? I tried new email? Came back un-reconized? So on the off chance put the old one back in? & hey presto it worked? Once gmail was open I read & checked email fro Firefox? I had changed password from link I used it to nip back & check new password? It worked? I now have one for access through Firefox & my old one through original sauce gmail on my old password? Its confusing I have no answers but now have two passwords? Firefox seems to have quite a few glitches? I don't know if this will help but though it may bring small comfort to know ur not alone in ur endeavor?
