(I'm not very good at English, if you don't understand something of my problem description please tell me). I have 2 OS on my PC: Windows 7 and Windows 8 RP (for the time of this question) - I keep Firefox synced between the two with Firefox Sync. Some days ago (at the time of this question) I changed some settings on about:config in 7 and denoted at the next day that these changes were missing on 8. I already know how to move "prefs.js", but I wanted to know if there was any possible way to sync my about:config settings between these 2 and continuosly and keep them synced on the cloud so whenever I make some change it applies for both systems. If possibly by Firefox Sync. (In other words: Sync "prefs.js" between my 2 OS).
