I put "bookmarks" for the subject but that's just because none of the other options adequately describes my situation! I just got a new MacBook Air. I hate Safari, so I always use Firefox instead as my main browser on Mac. Have been doing it for years. This time, I set up Firefox the way I wanted it, with a specific home page, logged into all my sites, emails, Facebook, youtube, etc etc, and set them all on my Toolmarks bar. ... Then a couple of days later, had to re-sign in to my computer due to downloading software, and lost everything I had done on Firefox! Had to re-sign into all my accounts again as well. Set everything up on Firefox again ... couple of days later, had to re-sign into my computer to due to downloading software ... lost everything I had set up on Firefox, had to re-sign into all my accounts. I would be so appreciative if anybody could tell me why this is happening and what I can do to fix it! I really love Firefox and don't want to give it up! Talked to Apple about it and they say it's not their issue. ... Thanks so much!!
