Fuzzfetch is a python tool for retrieving builds from the Firefox-CI Taskcluster instance.

Overview

Fuzzfetch can be used to retrieve nearly any build type indexed by Firefox-CI. This includes AddressSanitizer, ThreadSanitizer, Valgrind, debug, and Fuzzing builds for both Firefox and Spidermonkey.

Installation

pip install fuzzfetch

Simple Build Retrieval

To retrieve the latest build from mozilla-central built with --enable-address-sanitizer and --enable-fuzzing, you can use the following:

fuzzfetch -a --fuzzing

To retrieve the latest build from mozilla-central built with --enable-debug, you can use the following:

fuzzfetch --target js -d

To retrieve a specific revision from mozilla-central, you can use the following:

fuzzfetch --build 08471023c834
