mozdebug
Utilities for running applications under native code debuggers intended for use in Mozilla testing
Decision gist · record as of 2026-08-14
Yes, if you are working within Mozilla's testing infrastructure or need to automate native debugger attachment in a similar context. The low install friction, lack of vulnerabilities, and broad Python version support make it safe to adopt. However, the aging maintenance status suggests it is stable but not actively developed—verify that it meets your specific debugger and platform requirements before relying on it for new projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later; intended for use with native code debuggers in Mozilla testing contexts.
- Low install friction with a pure-Python wheel distribution.
- Maintenance status is aging—last release was 207 days ago—but the package supports current Python versions through 3.13 and carries no known vulnerabilities.

What it is and what it does
mozdebug is a utility library from Mozilla's testing infrastructure that wraps the mechanics of launching applications under native code debuggers. It abstracts away platform-specific debugger invocation and configuration, allowing test harnesses and automation to attach debuggers consistently across different environments. The package depends on mozinfo and mozshellutil to handle system detection and shell utilities.
It is intended for developers and test engineers working within Mozilla's testing ecosystem or similar native debugging scenarios. The package has been stable since its initial release in 2015 and supports Python 3.8 through 3.13, though its aging maintenance status suggests it may not be actively developed beyond bug fixes.
Use it for
- Attach a native debugger to a process during automated testing without platform-specific shell scripting.
- Integrate debugger launching into test harnesses and CI/CD pipelines.
- Standardize debugger invocation across different test environments.
- Debug crashes in compiled components during test execution by automating debugger attachment.
