Places an unremovable ad for the extension's premium tier features over every fic you read, in the form of a crown button in the lower left corner of the screen. There's no option to remove it without paying up. Thus, this extension is monetizing ao3 and ao3 authors' work, which is a terms of service violation, disrespectful, and at worst could risk drawing legal trouble for ao3 and the fanfiction community more broadly. I don't mind too much that it has premium features in the first place, but placing an ad over ao3, and especially over the text of fan authors' works, without permission is absolutely too far.

Is AO3 Advanced Marker 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.

AO3 Advanced Marker 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.

AO3 Advanced Marker is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
