Extension safety

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.

Power Thesaurus requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge 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 an Edge add-on.
