Unable to Sync. HELP 1. MacBook syncing is ON, but iPhone doesn’t recognize new Firefox password so I cannot sync via email. 2. When I use scan option, I do not receive a code on my MacBook. 3.  When I attempted to scan two or three weeks ago  (the beginning of my sync mission), The code appeared but the sync failed. Instead of code, I got the spinning wheel. Please advise me re solving this problem Thank you!
