Do any of you have thoughts on a business case for continued use of Firefox for an individual?

Why? My employer is moving to uninstall all instances of Firefox on company computers for ‘security reasons’ in favor of Edge and Chrome. I would be allowed to keep it if I could make a business case for it. There is no legit reason why I can’t get my work done with another browser, but I am going to push hoping just being a squeaky wheel is good enough. My guess is folks on here will have clearer thinking on this than me. Does anyone out there think my IT dept is making a good decision?
