It's really not. Small businesses exist.

If you have the resources to develop an internal company addon, you have the resources to build a firefox that accepts a different signature.

Respectfully disagree - having to rebuild each time patches come out, on multiple OSes and versions, which have a patch to allow unsigned extensions is a massively more time expensive than developing a browser extension, and requires extra knowledge on the behalf of the persons responsible

Luckily it's not necessary: you can still enable a flag in ESR releases that allow installation of unsigned add-ons, so that solves it for company-internal tools.
