Is it possible to sync UbuntuOne contacts with Thunderbird's address book?

3 Answers 3


Michael is correct. Thunderbird doesn't integrate with CouchDB (yet :) so the only way to get it to sync with the Ubuntu One cloud is through our mobile phone contacts sync service since Funambol (our technology partner) has developed an add-on for that application. They also have add-ons for MS Outlook and the Mac Address Book applications.

Currently their add-on does not support Thunderbird 3 (so jumpnett is correct) but they're working on supporting that version of the application.


  • As of ~Nov '11 / Thunderbird does integrate with Couch DB. I'm on Version 9.0, Ubuntu 11.10 and integration is definitely in place.

It is supported, but not quite as elegantly as Evolution syncing. Here's the step-by-step:


Basically, you must tell Ubuntu One you have a mobile phone (you can fake it) and then install the mobile phone syncing plugin for Thunderbird and point it at Ubuntu One.

    The Funambol Add-on mentioned in the link isn't compatible with Thunderbird 3.1.2.

  • As of Nov 2011, this answer was no longer accurate. Ubuntu One discontinued mobile support (temporarily, they swear) and Thunderbird 9 integrates with CouchDB.

As of 11.10 (a year and a half after you asked) the answer is a resounding "yes." At this stage integration works well.

  • I'll have to check it out, but I don't know if it's necessary for me anymore. I have since started syncing my contacts through gmail with an extension, but it's nice to see Ubuntu making progress.
