Odoo Toolbox is a Firefox extension designed specifically for Odoo developers and Odoo.SH users, providing a suite of tools to improve the development experience. Key features include an advanced DevTools panel for Odoo RPC testing and data exploration, as well as a technical sidebar that offers field inspection and database context information.

Overall, Odoo Toolbox significantly streamlines the workflow for developers working with Odoo.
