FIREFOX will not show ZOHO database but EDGE will

I've been unable to work on my several (12+) ZOHO Creator database for some time. Now when I try - FIREFOX will not open any database. So I switched to EDGE and they work perfectly.  I have no idea what browser my viewers will use so need all to work as they formerly did.  What is wrong with FIREFOX ??
