I don't know. Like another comment here says, some companies have been blocking Firefox because it's difficult to bend it to their will. For them, a browser has always meant one thing: Chrome. With Firefox entering the mix now, it's going to be 'yet another browser when we already have one'. Most corporate admins, I'd think, will say 'no, thanks'.

I once had to work with group policy FF that prevented me from configuring the way FF started. I wanted it to keep the session, but instead it always started with a blank slate. Mind-blowingly stupid.
