I can't get Firefox Sync working between my N7 and laptop (Sony Vaio Win 7). I get it set up on the N7 and see the codes. Then on the laptop, I enter the codes, which causes then N7 to go into waiting for other device mode, so it sees something. Then on the laptop it takes me to the account screen and when I press 'I have an account' it does nothing. If I press 'setup a new account' it opens the screen, takes the info, and just goes away. I have FF 16.01 and just got the new FF beta push on my N7, so I'm up to date. I've been trying it since I got the N7.
