Rated 3 out of 5 stars

I have used this plugin for over a year without issue but since the last Thunderbird upgrade (31.2.0) I am suffering with thousands and thousands of duplicate contacts if I create the new contact through Thunderbird. If created on my Android phone or gmail web there is no issue. "Merge duplicates" is enabled in gmail web as is "Check duplicates before adding/modifying a contact" in the plugin options. It would have been a five star rating but this elementary bug that has crept in results in a three.
