It was just after WannaCry was big news. They had installed some Blucoat or something along those lines. I think Firefox didn't play so nice with the monitoring software hence it was classified a risk. I have to add that the Security Director wasn't a security expert, highly ambitious and was never going to entertain anything he didn't understand.
