I have a Gmail Contact Group with a number of existing members. When I try to add a new member using Firefox, it does it but when I then manually sync them in Thunderbird, it removes them from Firefox's display: is this a bug in gcontactsync?. When I try to add them in Thunderbird by first creating them in Google Contacts address book before dragging them to the group's 'folder' of Google Contacts address book, it doesn't let me: is this a bug in Thunderbird?

This review is for a previous version of the add-on (0.3.5).
