September 2025 monthly summary for ghostery-extension focused on feature delivery and code quality improvements. Key feature delivered: Adblocker now supports scriptletGlobals.warOrigin by obtaining a dynamic extension ID for web-accessible resources and injecting the global variable into scriptlets. Tests were added for custom scriptlet filters that rely on this global, improving confidence in dynamic resource handling. Major bugs fixed: No separate major bugs reported this month; work centered on feature delivery and test coverage. Overall impact: Enhanced reliability and flexibility of the Adblocker scriptlets, enabling dynamic resource mapping and improved filter customization. This reduces maintenance burden and prepares the ground for future dynamic scriptlet enhancements, contributing to better user experience and security posture. Technologies/skills demonstrated: JavaScript/TypeScript extension development, dynamic extension/resource handling, scriptlet injection, test-driven development, and test coverage expansion for scriptlet filters.
