Thanks for the reply. I am not super tech savvy with this stuff so I tried all I could figure out how to do. Went through settings and turned off pop up blockers, added AXS to the list of allowing pop ups. Nothing has seemed to work. Its just crazy to me that it will work in Safari and not Firefox. Trouble shoot mode had the same issue, but I'm not surprised as I downloaded Firefox and only added two extensions for grad school.
