Updated to 96.0 this morning, then tried to log in to FedEx website. After hitting "log in", I get an error message that says:

 Http Failure response for https://api.fedex.com/user/v2/login/validate: 0 Unknown Error

I then used MS Edge browser and had no problem logging in.

Some websites just don't like Firefox. Some users have gone as far as changing their User-Agent to get those sites to work. (Are they jealous perhaps?)

I have several versions of Firefox and had no problem.


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