Features & Capabilities

AMO-Safe is a small, AMO-friendly extension skeleton. AMO-Safe demonstrates best practices required by Mozilla's add-on policies: it requests only the storage and activeTab permissions, keeps all JavaScript in external files (no inline scripts), avoids unsafe DOM APIs such as innerHTML, and never loads or executes remote code. The popup provides a safe action to copy the current page's title to the clipboard and to inject a compact content script on user gesture for highlighting the currently selected element. The options page stores a user-configurable highlight color in browser.storage.

Is AMO-Safe Skeleton 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.

AMO-Safe Skeleton does not require any sensitive permissions.

Risk impact analysis details

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.

AMO-Safe Skeleton may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
