User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:30.0) Gecko/20100101 Firefox/30.0 Waterfox/30.0 (Beta/Release) Build ID: 20140708101823 Steps to reproduce: Trying to write a message to a contact from Google Mail account, where that contact has three e-mail addresses defined. I have my address book synchronized by add-in, but there is no space for more than two addresses in the address book. Actual results: Third address is not recognized by Thunderbird. I had to go to web version of GMail to extract the address from my address book there. Expected results: Contact should have as much e-mail addresses as I would like to have, like Google Contact. So synchronization of e-mail addresses would contain them all.
