I don't know. Ironically, I had Normandy enabled (without my knowledge) and that "hotfix" they supposedly rolled out didn't reach my own client. So, what ever that feature is for - it doesn't even work. Apparently you also need to have "studies" enabled as well. It didn't work either. So, I'm waiting for official updated release. If they don't fix this soon - I'm done with Firefox and Mozilla.
