Features & Capabilities

Nightly Tester Tools (NTT) is a Firefox add-on designed to assist testers working with Nightly builds of Mozilla applications. It offers features such as copying the current build ID or listing installed extensions directly to the clipboard via a toolbar button. Additionally, users can insert this information into textboxes using the context menu and customize the browser's title bar for easier identification.

This extension supports multiple languages including English, Chinese (Simplified), Czech, Japanese, Polish, Russian, and Swedish. While it provides essential functionality for Nightly build testers, some features from the original XUL-based version remain unimplemented due to WebExtensions API limitations. For more details and source code, visit the Mozilla Wiki and the GitHub repository.

Is Nightly Tester Tools 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.

Nightly Tester Tools requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

Nightly Tester Tools has earned a fairly good reputation and likely can be trusted.
