The original inspiration for this extension came from a comment I saw online about a Chrome extension that changes New Tabs to show your age, the global population or a countdown to a certain date. The name of the extension is Morality. 

Simply put, Memento Mori is a new tab extension that aims to remind the user of the brevity of life. With every new tab, a countdown is shown. This countdown shows you how much time you have left before you die.
Risk impact

Memento Mori requires very minimum permissions and is relatively safe to use.

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, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Memento Mori has earned a fairly good reputation and likely can be trusted.

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 Browser Add-ons, 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, especially ones with higher risk impact and/or higher risk likelihood.
