What you say is what I do, Firefox is open all the time, I switch to brave or edge if ff won't load something. I use adnauseam as adblocker.

I have never had chrome on windows 10 or 11; nor chromium.

For a year chase.com wouldn't allow me to login from Firefox. Dumb.

Did you go to your local Chase branch with Firefox on your phone and pretend you have no idea why it doesn't work?
