Hello, I had Firefox Sync set up at work on my work computer (windows). I want to set up sync at home on my MAC. I no longer work at my previous job...so, I have no access to that particular computer. I didn't realize that sync was specific to the device...I thought I could just sign on to Firefox at home and sync but nothing happens when I do. I haven't paired this MAC...don't think I was asked too and can't find directions that work. Is it a MAC to PC issue or am I missing something? Thanks so much for the help.
