During their two-month contribution to mozilla/gecko-dev, Meacer focused on enhancing Content Security Policy (CSP) reliability and security. They developed comprehensive end-to-end tests for CSP URL hash allowlisting, covering directives such as script-src, default-src, and script-src-elem, and verified correct parsing and application of URL hashes in both header and meta policies. Using JavaScript and HTML, Meacer also addressed a CSP bug affecting URL hash handling on initial URLs, expanded test coverage to dynamic scripts and redirects, and refactored test infrastructure to improve maintainability. Their work deepened CSP test coverage and reduced regression risk in security-critical script evaluation.

Jun 1, 2025June 2025 monthly summary focused on strengthening CSP URL hash allowlisting testing in mozilla/gecko-dev. Delivered end-to-end tests for URL hash allowlisting across CSP directives (script-src, default-src, script-src-elem) and interactions with header/meta policies; verified parsing and application of URL hash-based allowlisting in script-src(v1) (commit 78ab26fd47a45357f276e627a535a46fb658238b). This work mitigates a CSP-related security risk and improves correctness of script source evaluation.
