User Reviews

Looks like an unsuccessful mirroring to circumvent Chinese laws banning the use of wide-spectrum add-ons against web content. Only the add-on's author and ID have been changed in the code - it does not bear the hallmarks of pasting malware visible to the simple “diff” command.

Is uBlock Origin 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.

uBlock Origin requires a lot of sensitive permissions. 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.

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