Mozilla Firefox enforces a strict policy: only human developers can commit code to the repository. No AI-generated commits allowed in production. This is a hard stance on code accountability—every line must be human-reviewed and human-authored before merging. It's a direct response to the flood of AI-assisted coding tools. The reasoning: maintain code quality standards, ensure legal clarity on authorship, and prevent potential security risks from unchecked AI outputs. Firefox is drawing a clear line between AI as a coding assistant versus AI as a direct contributor. Interesting precedent for open-source governance in the LLM era.
