Rated 2 out of 5 stars

Not clear whether the bogus nobody@nowhere.invalid emails addresses are added to our Google account. These are my phone contacts! I don't need a bunch of junk messing up 100's of contacts. Too much work to risk it. I loved this addon before. Too bad.

This review is for a previous version of the add-on (0.3.3). 

These e-mail addresses are only stored locally in Thunderbird to work around mailing list bugs/assumptions in Thunderbird. They will never get propagated to your Google contacts.
