*  Code Test Studio: Preview and test code in a safe environment before applying them to your project. Verify that everything works as expected before using the updated code.

Is ERION AI 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.

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

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.

ERION AI is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
