I am a teacher and our school district uses Sunguard's Eschool 360+ and for the last 7 years Firefox launched this page with no issues. Firefox enables to me to enter this site using a PC at work, but will not allow me to enter the site using my 2012 Mac BookPro that is running OSX 10.9.5. I have contacted our database manager and they seem to think the issue is on my end with Mac/Firefox I have tried the following, which I thought might case issues or be related to older versions of the program. Uninstalling reintsalling Firefox Cleared cache and histories Deleting bookmarks to any Eschool site Deleting keychained passwords on system and the system. No luck. Any help is appreciated
