As an instructor in Blackboard, everything works EXCEPT posting an annoucement or toggling in and out of edit mode. Works in Chrome.

When I click on "Create an announcement" in Blackboard, Firefox opens a new tab "about:blank." When I click on the "edit" toggle switch, the screen flashes and nothing happens. Everything else seems to work fine. I have no issues like this when using Chrome. What could be the issue and the fix? I would really rather not have to go back to Chrome just to use Blackboard. BTW This is occuring on both my MAC and my PC. Thanks!
