403 error on xero.com login service
I and some colleagues using firefox get a 403 error when switching to xero.com authorization services.
1) There is no error in other browsers and with postman. 2) On all versions of firefox, error 403. 3) When installing a clean isolated system on a virtual box - error 403. 4) The error occurs on any connected network. 5) WireShark showed packet loss: (on screenshot).
Technical features: 1) Windows XP (x32),Wwindows 10 (x64) 2) Firefox versions: 52.0-92.0 (latest)
P.S. Xero recommends that you contact you directly for assistance. Because not all users get this error under firefox.

I have several versions of Firefox and had no problem.
When I click on xero.com I end up at https://www.xero.com/us/ Where do you end up?
There is security software like Avast, Kaspersky, BitDefender and ESET that
intercept secure connection certificates and send their own.

Still no problems.
Today I installed version 92.0 on three different computers with different OS and different connection providers - the problem repeated itself. I think this is no longer a local problem and soon they will really be interested in it.
