As of 2 months now, two different bank websites I try to log into are always impossible to log in using Firefox desktop browser - whereas, no problem at all using Google Chrome to do those logins. In one bank site, a 404 error page pops up upon trying to login. In the other site, the site simply ignores the entered login details and stalls on the login page.

What did Firefox updates do that created that consistent problem? I've done the usual cookie cache cleaning/ restart process, but the problem remains.

I see in other similar problem threads, that the problem was overcome by users who switched back to Firefox 86. Seems to mean that this is a firefox bug that initiated in version 87.....?

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
