Sync is set up correctly between my iMac desktop and MacBook. I changed passwords this evening for a website on my mac desktop, but after several minutes the website saved passwords on my MacBook had not updated yet. I refreshed the saved logins page on my MacBook several times, but no luck. I started with a new tab and checked the saved logins again but they still had not updated. I eventually went back to preferences, to sync, and selected sync now, at which time they updated instantly.

How many minutes should it take for Firefox to update passwords automatically on its own across all devices without manually having to select sync now? The help pages indicate that sync should update changes automatically when Firefox is open, but after 10 minutes that did not occur on its own. I have high-speed xfinity internet service with excellent wi-fi capabilities, so there was no problem on my end. Thank you.
