Since the latest Firefox update, it has frozen the app & crashed my computer multiple times within a few days; it has also caused problems logging into my primary bank account ("access denied") but has nothing to do with the bank (I called the bank; no problems there, but they suggest using Chrome browser. NO WAY!) Every time Firefox has updated the past few months, it has interfered with my password vault’s proper functioning {Last Pass}. I am using a late 2012 Mac mini, running OS 10.15.1 (the newest acceptable OS for my computer). I attribute some of the problem to their adding a number of new features without making certain the basic app is stable.
