Sure, this app can get unstable after each update of both google and Thunderbird. But Every time, after a new clean update or re-install of the app, it works great... The developper achieves new working updates. Fresh installation needs couple tries, because there's no manual to make it easy. Perseverance is the key word ! Try all install solution until good result :-)
