It looks as if things are not going too well between Facebook and Google, especially as Google are now looking at getting into the social networking business. The first move has been to stop the migrations of its users by blocking a Chrome extension that provides this service.
According to Mohamed Mansour, who created the “Facebook Friend Exporter” Chrome browser extension;
“Facebook is trying so hard to not allow you to export your friends” he announced, “they started to remove emails of your friends from your profile by today July 5th 2011. It will no longer work for many people.”
Apparently, it will not be that long before a Chrome extension pops up and it will have to start all over again.
