SO many corporate/govt websites do this. My health insurance and credit card company do it. It’s mind boggling. I always keep some variation of Chromium installed to deal with it and then go back to LibreWolf.
I’ve not used LibreWolf, but assuming that Firefox addons are generally compatible, it might be worth trying Chrome Mask. It’s made by a Mozilla employee.
I will give this a shot!
Doesn’t Firefox automatically spoof your browser when it has been reported to work better?
