No way of deciphering or determining what in the heck triggers it or why - way way too many factors and settings and variables both within the FF registry and the macOS and the activity I may or may not be doing at any given time.

Sometimes FF after fresh down load from the official FF site for MAC will work great for an hour or half a day and then out of now where go into the spinning beach ball , and unable to enter data into any field - completly bricked and FF status shown as Not Responding. Tnis could happen immediately, or after an hour or anytime within a day or two. No way of deciphering or determining what in the heck triggers it or why - way way too many factors and settings and variables both within the FF registry and the macOS and the activity I may or may not be doing at any given time. I will say I experienced this when all apps on my MAC were shutdown, no apps up and running, but I do use Backblaze, Mai Backup X, Malwarebytes, Dropbox, MS NTFS Tuxera, DriveDX which all have ongoing background tasks running all the time or at least in the background from time to time. However, I have used this setup for the last few years with Firefox MAC with absolutely no hiccup whatsoever. And then immediately after the last FirForx update on Tahoe, just before I applied the latest 16.5.1 Tahoe upgrade is the intermittant freezing with FF started. Could this be a FF / Tahoe incompatibility issue? If not, does anyone out there have anything to fix this? And yes i did a complete uninstall of all of FF hidden Library folders as well as the "firefox.app" itself - if anyone tells me to uninstall all the hidden FF folders and files in ~/Library one more time, then forget it, I am done using FireFox. Been there and done there a number of times the last week, exhausted with that, and doesn't do a thing. And yes kept deleting and creating new FF profiles and did not fix the issue. So does some great genius Mozzilla FF Mac SW engineer have any clue as to the real issue and the real fix without sending me on a wild goose chase? thank you. clb6
