Maybe not what they intended, but it surely looks like Mozilla is trying to actively hide LLM-driven changes to Firefox (see https://phabricator.services.mozilla.com/D279515). The claim is that this is only about attributable ownership to a human (according to a Mozilla employee in https://github.com/mozilla-firefox/firefox/commit/71cc24b6a400dbd434e4df37087960d94b764791#commitcomment-178280554).
The optics are, once again, terrible.
They are getting heavy pushback after their CEO announced that Firefox will “grow from a browser into a broader ecosystem" and become an “AI browser”.
