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.
GMX MailCheck 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.
GMX MailCheck has earned a good reputation and can be trusted.
