TSP Website Issue - Firefox Only

Macbook Pro running 10.15.6, Firefox 80.0.1 (64 bit), Bitwarden Browser Extension 1.45.0

Ok, so I am having a problem in Firefox only (Mac only) - this works perfect in Chrome - so not sure what the difference is. I disabled all extensions with the exception of BW and still the same.

I have a custom field set up (see attachment) for secure.tsp.gov to select the User ID radio button and it will not work in FF. The userid and password fields get populated properly, but the UserID radio button doesn’t get selected. Like I said… works perfectly in Chrome. Any ideas?
