Spoke directly to the devs, and they are aware of the one specific method which nullifies Firefox's use. They are working to eliminate the use of that one method, so at least they are not complacent with just accepting Chrome or bust.
Unless this is a very low level package, I find it hard to believe it just doesn't work with Firefox in 2023, at least if we are referring to the basic browser APIs for rendering, interpreting, sandboxing, etc.
In other words, if they aren't doing something systems level that exposes significant differences in the underlying browser APIs, then what's the cause of the issue?
Most application level differences (with the exception of the adware) are very very minor. That didn't used to be the case, but it certainly is today. I.e. you would have to put some effort in/intentionality is usually required to break something in Chrome but not Firefox and vice versa as a standard user program. Its not recommended, but I rarely see front end folks doing the same kind of browser tests that used to be industry standard these days, because it simply isn't an issue and if it is, it's because you are knowingly using a non-standard feature (which is usually adware related). The fact that they figured out the cause so quickly implies it's something like that. Systems level issues would require significant time to investigate and probably the involvement of experts in modern browser implementations.
Just my two cents as an ex front end guy.

There's no such thing as an ex, just one in recovery
I am used to accessing my Chase bank account through Firefox. I just checked, and I am still able to log in fine, including with a variety of privacy-enhancing extensions that break many other sites. What problems do you encounter?
But all they’re doing is user-agent parsing.
Just lie about your user agent (using an extension) and chase will let you login, their site works fine with Firefox.
Allow Firefox to send technical and interaction data to Mozilla
Allow Firefox to make personalized extension recommendations
Allow Firefox to install and run studies
Allow Firefox to send backlogged crash reports on your behalf
But, let's give them a pass because they're not based on Chromium.
