i have the same problem. does anybody find a way?
Thunderbird ESR has now been merged with the main Thunderbird releases.
Install old version, sync contacts, update TB.
For those on 24 series or ESR 24 you can use SOGo frontend addons to sync address books via DAV.
Grab it here:
Go to Address Books -> File -> New -> Remote Addressbook
Set name to whatever you prefer and the url format should be:
Change "Contacts" and "User" to the book and user respectively. (Port is optional, only if used.)
If your Address Book has a space in it's name such as "Emailed Contacts" it should become "Emailed%20Contacts" in the URL.
Hope this helps!
it took me a really long time to get every bit of information synced between all my devices and last week i got even contacts synced with my thunderbird. There is the extension tzpush that works for me as i already had an configured z-push installation:
it's developed for zarafa, but works fine with zimbra. i ran into all the problems with zindus and sogo as everone else here, but this solution finally worked. it's a piece of work to configure z-push to extend zimbras foss capabilities and no solution for non-admin users, but if you're running your own zimbra server, i can confirm: this is working
