Would love to be able to backup my entire Firefox system to another computer. Personally I have an office machine, a home machine, a loungeroom machine, etc etc. My Office machine has many profiles set up, just right and It would be great to sync them all to all my other machines. I was told to just copy the Mozilla folder in Appdata/roaming to another machine, but Firefox on that machine was blank. I asked this question in the forum but no one seems to know.
