I've attempted to use the 'Find your friends' on Battlelog many times today but it simply won't work.
First of all, once I click the link to find my friends the page does not even load correctly -
I clicked the middle 'connect' link to try and find friends from Xbox Live. It takes me to the Microsoft login screen where I log in and after that just a blank white page appears. I acknowledge the recent Xbox Live disruptions, but if I wanted to find friends via Facebook there's no link for me to click (the screenshot). And even if I owned a PS3 it would display: http://gyazo.com/7189f5437cb7fc242224f55f90b08744 (whether that's due to the fact I've not got a PS3 account linked to Battelog I don't know - although I doubt it).
I have tried both Google Chrome and Firefox with no success.
