Hello,
In your log it looks like you added a
2 to the name of one of your contacts in Thunderbird and then updated or modified that card online through Google's interface.
What happens if you update a contact through Google's interface, wait for a minute or two, then sync?
Then try to update a different contact through Thunderbird, sync, then check it online. Refresh the page first and if that doesn't help Sign Out then log back in.
Also make sure the timezone you have
here matches the timezone on your computer.
