Yeah, I’m also a web developer and this person is completely up their own ass. We’ve all struggled with browsers that lag behind standards (internet explorer) or implement them in weird ways (safari). But Mozilla has never even come close to being a problem like the others.
Also I doubt they are using the newest of new web standards that would actually need to be poly filled and even then with modern JS build tooling poly filling isn’t difficult or abnormal. Oh, the bundle for your crappy SPA might be a few kb bigger but that isn’t gonna make a difference.
