I'm sure this is great for improving adoption on the admin side, but I'm also sure that I would hate using a locked-down Firefox.
My company has management software that nags me about the latest Firefox version, which is annoying, because I use the extended support release instead. Less frequent updates, and fewer sudden changes like the AI features people have been grumbling about.
Incidentally, 153.5.0esr was released today, with 140 reaching EoL.
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.
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'.
