Amazingly (or perhaps not), Firefox (macOS 106.0.1 (64-bit)) slammed me back to using Google as its toolbar search engine. I had been using DuckDuckGo for years.
Luckily Firefox had a pop-up telling me as much, actually bragging about it, so I knew to set it back. But I did test it once before swapping, and this was not a drill. The update to Firefox wasn't showing me the wrong dialog; it had slammed me back to Google.
/sigh
Profiteering weirds the internet.
