Push contacts to Google from local

Question

I am able to synchronize Thunderbird with my gmail contacts such that I can use all of my gmail contacts in Thunderbird.

I have made changes locally to my contacts locally in Thunderbird. How can I export those changes to my gmail contacts?

Answer 1

I'd recommend the Google Contacts add-on for Thunderbird

Access bi-directionaly to Google contacts via address books. This extension detects gmail accounts which have already set up and creates address books for each of them. Cards in the address books are synchronized with Google contacts; they represent the current Google contacts contents and Google contacts will be modified when you modify the cards. TB's mailing lists and Google's contacts groups are synchronized in the same manner.
