Is OpenSea 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.

OpenSea requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • High Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk.
  • High ******* ****** ** *** ********* ******** ***********
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.

OpenSea may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
