It abstracts away the complexity of navigating Taskcluster namespaces and build metadata, letting you specify a branch, build date or revision, and build variant (debug, AddressSanitizer, ThreadSanitizer, fuzzing, coverage, etc.) and get the matching artifact. The tool supports multiple operating systems (Android, Darwin, Linux, Windows) and CPU architectures, and can search for the nearest available build if an exact match isn't found.\n\nThe package is designed for security researchers, fuzzing engineers, and developers who need to test against specific Firefox builds or variants. It depends only on pytz and requests, making it lightweight to install. The tool runs as a CLI with a rich set of options for targeting specific builds, and also supports dry-run mode to inspect metadata without downloading.","worth_installing":"Yes. Fuzzfetch is actively maintained, has no known vulnerabilities, low install friction, and solves a real problem for anyone working with Mozilla builds. The MPL 2.0 copyleft license is standard for Mozilla projects and poses no barrier to internal use or testing. Install it if you regularly need to fetch Firefox, Spidermonkey, or Thunderbird builds from Firefox-CI."},"id":"fuzzfetch","links":{"html":"https://skillfed.io/packages/fuzzfetch","md":"https://skillfed.io/packages/fuzzfetch.md","pypi":"https://pypi.org/project/fuzzfetch/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-12-11","license_spdx":null,"license_treatment":"copyleft","name":"fuzzfetch","python_support":"supports_current","summary":"Downloader for firefox/jsshell builds."},"popularity":{"monthly_downloads":95635,"position":13259,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"16.1.0"}
