Features & Capabilities

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.

Is Page Performance Test Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Page Performance Test requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Medium ****** ** ********* ****** ********* *** **** ****** **** **** ** ******* ** ********** **** ***********

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Page Performance Test has earned a fairly good reputation and likely can be trusted.
