Just needed to re-install after firbird update and life goes-on.
I hope Mr. Kewish will keep on updating this add... The day he will be too tired of doing this, we will all cry for such a solution , the only one which connects our google-agenda with firebird... Thank you Mr. Kewish ! GG

Just update last Google Calendar Plugin and reconnect: works like a charm.
With new outcoming Thunderbird's updates, DO NOT update the very first day but wait 10 days. It gives developper's a bit of time to test their module's update.... That's it
