This skill equips developers with the knowledge to design, implement, and test Thunderbird WebExtensions that adhere to MV3 standards, ensuring compatibility and maintainability.

Core Features & Use Cases

  • Best practices & governance: Understand how to avoid Experiment misuse, apply i18n, and manage permissions for a smooth review process.

Quick Start

Create a minimal Thunderbird WebExtension with a module background, a simple popup, and i18n localization, then load it into Thunderbird for testing.
