can anyone recommend a good Thunderbird extension which allows for
synchronizing the address book with Google mail? So far I tried Google
but something went wrong with the syncing and some contacts where
deleted on both sides. To avoid this problem, one can use Google
Contacts in read-only mode (it will only fetch contacts from Google, but
never write to it) but then you have to import new Thunderbird contacts
to Google mail manually.
December 2012, which allows for syncing of contacts, but since
Thunderbird's development is apparently on hold this is probably not
gonna be supported out-of-the-box. There are some other extensions for
Thunderbird, but since synchronization is hard and a lot more
complicated than: "replace newer version with older one" I'm looking for
something mature and well tested.
Before someone suggests it, I know Evolution has this feature built-in.
I gave it a try last week and found so many other grave bugs with the
calendar and newsgroups that Evolution is simply unfit for my needs. I
really like Thunderbird and want to stick with it for a few more years
until I have to look for something else.
