Firefox CLI is my new project - a CLI interface that lets your agent control your real Firefox session.

It's a full equivalent of Agent Browser with the same capabilities, but for Firefox - and with a number of improvements.

Why it's better

First, you install the extension once and for all. The extension ships right alongside the CLI: install it, grant access, forget about it. Unlike Chrome, where you have to grant connection permissions every half hour and manage debugging sessions - here it's one button and full control.

Second, your agents can now create their own separate windows and request your permission to connect on their own.
