When I started having this problem logging into a certain credit card co.'s website beginning with about Firefox 105.0.2 on Fedora 38, I was told by their apparently outsourced customer service that I had to use Chrome, which I don't have installed there and couldn't try. Yeah, they wanted me to use LogMeIn so they could fix the problem, too. Right.

Firefox on Android was still working, though, loathe as I am to put passwords of any significance on my phone. Doesn't directly address your question, which I'd like to know the answer to as well.
