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.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Similar problem here. FedEx login not possible on Firefox. No issues on MS Edge.

I've tried all the usual "fixes," but there are simply some websites that routinely do not work with Firefox.

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.
