New Tab - Back to the Future 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.
New Tab - Back to the Future may not be trust-worthy. Avoid installing if possible unless you really trust
Risk likelihood measures the probability that a Chrome extension may turn malicious.
This is determined by the publisher and the Chrome extension reputation on Chrome Web Store,
the amount of time the Chrome extension has been around, and other signals about the
Chrome extension. 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 Chrome extension, especially ones with higher risk impact and/or
higher risk likelihood.
