Must have.
Please make it work with TB 60! Please!... ;)

Questa recensione riguarda una versione precedente (3.0.0) del componente aggiuntivo. 

This add-on does not work properly in TB 60.0 and later. I'm tracking my progress towards supporting 63+ in https://github.com/jdgeenen/gcontactsync/issues/121. Thunderbird's rate of making breaking changes has outpaced my spare time, so your patience is appreciated.
