mozdevice
Mozilla-authored device management
Decision gist · record as of 2026-08-14
Yes, if you are already part of Mozilla's testing ecosystem or need to maintain existing Firefox test infrastructure that depends on it. No, if you are starting a new mobile test automation project—the dormant maintenance status and lack of active development make it a poor choice for new work. Consider it only as a legacy dependency or when integrating with existing Mozilla tooling.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a connected device or emulator to be present; the package itself has no strict Python version requirement declared, but supports Python 3.8, 3.9, 3.10, and 3.11.
- Low install friction with a pure-Python wheel distribution.
- Maintenance is dormant—last release was 645 days ago—so expect no active bug fixes or feature updates, though the package remains functional for its intended use.

What it is and what it does
mozdevice is a Mozilla-authored library for managing and controlling connected mobile devices and emulators. It abstracts the complexity of device communication, allowing test automation and tooling to interact with Android devices and emulators through a unified interface. The package depends only on mozlog for structured logging, keeping its dependency footprint minimal.
The library is part of Mozilla's mozbase testing infrastructure and is primarily used within Firefox testing workflows. However, its maintenance is dormant—the last release was over 645 days ago—meaning it receives no active development, bug fixes, or feature additions. It remains functional for existing use cases but should be considered stable-but-unsupported; if you need active maintenance or modern device support, you may need to fork it or seek alternatives.
Use it for
- Automate testing on connected Android devices or emulators in CI/CD pipelines for Firefox or other projects.
- Write test scripts that push APKs, run commands, or collect logs from multiple devices in parallel.
- Integrate device control into custom test harnesses that need to interact with mobile hardware.
- Manage device state and lifecycle (reboot, clear data, install apps) programmatically during test runs.
