foxrunner — agent tasks that resume bởi Pooria

foxrunner is the reference add-on for the foxrunner library. It shows durable tasks for AI agents and other long jobs in a browser extension.

Who it is for: developers who build agents or extensions with tasks that take minutes or hours, and anyone who wants to see how such a task survives a restart.

What it does

• Starts a sample task from the popup. The task has five steps: prepare, a slow step, a wait of 2 minutes, a step that fails two times before it works, and finish.
• Saves the state of each step before it starts and after it ends. When Firefox unloads the background page, or restarts, the task goes on from the last finished step.
• Retries a failed step with a back-off.
• Waits with an alarm, so no timer keeps the background page loaded.
• Lists each task with its steps, attempts and status. You can pause, resume and cancel a task.

Close the popup while the task runs: the task goes on.

What leaves your computer: nothing. Tasks and their state stay in the add-on's local storage. The add-on has no server and no analytics.

Permissions

• Storage: keep each task and the state of its steps.
• Alarms: wake the background page for a wait or a retry.
