I should have mentioned in my original post that I have had issues with Safari crashes on my MBP16 M1, since the very first day. Safari would immediately freeze on various websites, but could potentially freeze on any website. The issue only became much more prevalent following the "emergency security update" of Monterey 12.2. Following that update, Safari, for all intents and purposes, became totally useless. Fortunately, I was able to force quit the Safari app, without having to restart the entire OS. As long as I only used Firefox, everything was OK (other than various less critical issues).
Over time, I scaled Safari down to the bare essentials: NO extensions, no pre-loading favorites, etc, etc. Nothing helped to remedy the issue.
Then, with the release of 12.3.1 (21E258) update to Monterey, all issues with Safari went away. So, while nobody in Customer Support was aware of the problems (or was allowed to admit to them), this update did solve my Safari problems!
I wanted to give it a few days before declaring victory, as one never knows what might happen as soon as you do so. But it would seem that someone in the development group actually read some of my numerous crash reports and figured out what was wrong.
THANK YOU, APPLE! It's good to be back in the fold! I've been using Apple products exclusively for far to many decades to ever consider returning to a MicroSoft product!
