> There are portable version of Firefox if you want to use it. Using that when you know the company has told you about their security policy forbidding it is, ummm, not wise. Especially not as a new hire. If work says "You use Edge, and are not allowed to use Firefox", then you use Edge, or you ask for an exemption from that policy if you have a good reason (and I'd want that in writing if it's an official security policy). Or you get a different job at a company without that policy.
