I have a Firefox Sync account set up and working on my home computer. This morning, I installed Firefox at work and would like to sync to my home computer. I don't have the key (and in previous versions of Sync, didn't need one - just needed to log in to my Sync account from the new computer). Is there a way for me to sync my work computer to my home computer without the key? It seems like Sync has really become needlessly complicated to set up.
