Can it sync two versions of thunderbird, one under vista, the other under ubuntu 9.04, on the same computer (dual boot)
This review is for a previous version of the add-on (0.8.10).You can sync both Thunderbirds with a Google account to keep them in sync. Or if you have Zimbra account you could use that instead of Google.
To create your own collections, you must have a Mozilla Add-ons account.
