I'd rather not have Firefox installed, than Firefox preloaded with MitM certificates, disabled uBlock Origin, Proxy Switcher, added Adobe, Copilot, and a few more "useful" extensions and security add-ons that can't be disabled, and so on.
If company IT gets hold of Firefox, it's not better than just using Edge or Chrome that comes by default.
hopefully the IT department pushes out uBlock Origin with whatever browsers they require people use. I used to push it out to several customers with the Chrome GPOs... although I know it doesn't work in Chrome anymore
