Perfection within reach! Rated 4 out of 5 stars

This is a very clever little extension. What it does, it does well. It is a clever workaround to some limitations in Thunderbird.

Unlike the creator, I do not want to use this with a phone; I use this to synchronize contacts in a small office instead of LDAP. As such, the decision to remove processing of mailing lists is a disappointment to me. It should have been made into an option, i.e., "Ignore mailing lists when synchronizing" and check or uncheck according to your needs. Also, when I tried to use it across a network share (Windows SMB) it took a long time to process and then didn't find anything to sync in the repository.

If those two things are fixed, it'll go from great to fabulous!

features? Rated 2 out of 5 stars

A lot of explanation with little clarity. I was hoping to be able to import vCard files with this, but cannot figure out how to do that, or if this add-on does that.

Great add-on! Rated 5 out of 5 stars

Love this add-on! I use it to sync my business cards. I scan them with ABBY BC Sync, export as vCard to folder, then sync this folder to Thunderbird Address Book via ThunderSync. This works without any issues!

Great! Rated 4 out of 5 stars

Very nice tool - many thanks! Export to vcard should be a default feature of Thunderbird. This add-on finally adds that capability.

Some feedback:
- Although the sync succeeds I get this error when exporting/importing to/from a single file: A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: chrome://thundersync/content/ThunderSyncVCardLib.js:402
(where the line number is different every time)
I just stop the script to continue.
- Would be nice if one could only sync e.g. accounts which have phone numbers. No need for all my contacts to be in my phone.
- It's strange you have to select an *existing* file when exporting to a single file: it might be the first export, so a file would not exist yet.
- Sync of contact goes wrong when displayname contains = (equal sign).
- Sync of contact goes wrong when email contains " (quote).

Excellent, but not perfect. Rated 4 out of 5 stars

This is an excellent Add-On. It would be perfect if it could sync individual contacts, rather than the entire address book.

This review is for a previous version of the add-on (2.0). 

Awesome! Rated 4 out of 5 stars

This is GREAT! A perfect addon for backing up contacts and allowing to easy off-line syncing with phones.The only reason I don't give it 5 stars is there's one niggly bit: When there is a difference, you need to change for each difference whether TB is exported or imported. I've found this very tiresome when I've simply emailed a lot to some people and the Popularity Index has changed. It would be nicer if there's a button to say "Import all" or "Export all", and if the startup auto-sync is turned on, there should be an option for "Always export / import".Other than that it would be nice if it could use not just standard files, but IMAP / LDAP / WebDav as well. But that's just a nice to have for me, not a train-smash.

Also it would be nice to have a toolbar button!

This review is for a previous version of the add-on (1.2.1). 

IMAP instead of files would be total awesomness Rated 4 out of 5 stars

It would be AWESOME if the source/target of these files could be IMAP-stored attachments. The new Thunderbird 3.3 API might help doing this, and that would allow thunderbird<->thunderbird transparent syncronization :-)

I use SVN+CRON to achieve something similar ATM, and as long as there are no conflicts, it runs just fine.

Very nice, BUT... Rated 5 out of 5 stars

Very Nice,
So pity it does not support Hebrew.
Would it support Hebrew characters in the future?

Work in Progress

In version 1.1 the user will be able to choose the preferred file encoding (ISO 8859-? or UTF-8) plus encoding handling in the vCard library will be reworked.
