Page Performance Test is a powerful WebExtension designed to measure the precise timing performance of any web page using modern Web APIs. It offers accurate charting of page load times across network, server, and browser phases, enabling developers and site owners to analyze and optimize website speed effectively.

Users can instantly save test results locally with timestamps for comparison across different test runs. Installation is straightforward through the Firefox Web Store, and it integrates with the browser's developer console for quick access. Additionally, the extension now supports activating performance tests directly in browser devtools, making it an indispensable tool for web performance auditing. A detailed video tutorial and related add-ons like Performance Map enhance the testing experience further.

User reviews

The add-on is appreciated by users needing performance metrics in older or limited browsers. However, it faces significant compatibility issues with recent Firefox versions, lacks clear output or results after running tests, has insufficient documentation, and presents usability challenges that hamper understanding and running it effectively.

Pros

Useful for grabbing performance metrics when browser developer tools are insufficient.
Works with older browsers like Waterfox Classic and TenFourFox which lack advanced performance support.

Cons

Not compatible with recent Firefox versions (e.g., Firefox 81.0.1 and Developer Edition 58.06.13).
No visible results or feedback after running tests, leading to user confusion.
Lack of documentation and support materials makes it difficult to understand and use.
Some users are unable to find or run the extension after installation, hinting at usability or compatibility issues.
