I have updated Firefox on both desktop and laptops. Signed out of Sync and back in. It works fine on WIndows 7 systems but nothing happens on Windows 10 system. I get the message that Sync will run momentarily but nothing I checked gets synced.

There is a way to take a look at any errors that might have occurred. When I tried to test this I received an Unknown Sync error and one of the add ons failed. If you open up about:sync-log in the browser you can share the file via pastebin.mozilla.org in a post for further troubleshooting.

My sync now works on Windows 10 after downloading the current Firefox version and then doing a Firefox refresh on the Windows 10 system
