In Sep 2025, delivered Brave Core CRX Packager enhancements for improved reliability and update readiness in brave/brave-core-crx-packager. Implemented robust download/unpack validation ensuring packaging only proceeds after a successful extension download, reducing build failures due to unavailable artifacts. Introduced publisher key support to sign MV2 extensions, enabling seamless Browser updates. Result: more reliable CRX packaging, smoother extension updates, and improved build stability for distribution pipelines. Technologies demonstrated include robust error handling, MV2 extension signing, and conditional packaging logic for improved CI reliability.
