CloseReview for Google Contacts by Victor Terber
Rated 1 out of 5 stars
Some time ago this was a pretty useful add-on, but for a while it does no longer work at all, as the user is asked for the Google contacts password in an endless loop.
No visible reaction from the developer despite numerous disastrous reports, so it seems that the application is no longer maintained. It was reported that the Google API that the add-on used (and which seemingly was now switched off) was marked as deprecated for years!
Besides the current severe problem this does not inspire trust that "simple" security problems would be handled appropriately, so even in case the app would be updated to work again I will longer trust my personal address book to this add-on, sorry.
