Features & Capabilities

This addon is experimental and not for general use. It was created to help Firefox developers by making this bug more visible: https://bugzilla.mozilla.org/show_bug.cgi?id=1383244

Namely, to make it more obvious when the idle timeout does not happen as expected when an add-on is using the WebExtensions idle API: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/idle

This extension shows an "all's well" notification when the idle state changes to active. If something went wrong and idle timeout did not happen as it should have, then no notification is shown. That is because with this bug the idle state never becomes inactive, so it never changes back to active (because it is already/still active), and thus there is no notification.

This add-on also logs changes to idle state to the console with a time stamp. This is another way it makes the occurrence of this bug more visible, and thus easier to diagnose.

Is Idle API Tester 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.

Idle API Tester requires very minimum permissions.

Risk impact analysis details

Medium Enables sending notifications which can be spammed but have minimal direct security impact.

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.

Idle API Tester has earned a fairly good reputation and likely can be trusted.
