I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration. I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to [http://example.com access] my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks
