how to synchronize contacts with thunderbird (and others)
I'm a new user. I searched userforum but didn't find answer. So here is my question:
Is there a possibility to have (active) synchronization with contacts in Thunderbird/smartphone/etc.? So if I add a contact in thunderbird it will be synchronized with cloud and then from cloud to eg. my smartphone? And bakwards, if I add new mobile number in smartphone, to be synchronized to Thunderbird?
