Features & Capabilities

AO3 Enhancements is a powerful Chrome extension designed to improve your experience on the fanfiction site ArchiveOfOurOwn.org. It adds various configurable tweaks such as displaying reading time and estimated finish time for works and chapters, along with published dates. Users can also view Kudos to Hits ratios for easy identification of top-rated works.

This extension allows advanced filtering options to hide works based on language, fandom count, author/pseud, and tags—with support for regular expressions. Several style customizations are available, including adjustable work width, columnar stats display, and forced text alignment for easier reading on large screens. Most features are disabled by default and can be enabled in the options menu on ArchiveOfOurOwn.org. Privacy is maintained as no data leaves your browser except AO3 itself.

User Reviews

Reviews commonly praise AO3 Enhancements for making AO3 browsing more efficient through robust tag blocking/hiding (including relationship tags), strong customization, and extra stats. However, the top issues are reliability and bugs (wildcard blocking not saving, occasional missing tags, dashboard disappearances, slow loads), privacy concerns around viewing other users' reading histories and login/logout controls, setup/instructions clarity, and gaps in features (blockable fandoms/characters, mobile support). Overall, highly valued and indispensable to many, but stability and privacy-related improvements would help.

Pros

Improves AO3 browsing experience with a smoother, more efficient interface.
Tag blocking and hiding is powerful, including support for hiding relationship tags.
Strong customization options and settings.
Extras like user stats/reading progress and wider screen optimization add value.
Widely regarded as indispensable and among the best AO3 extensions.

Cons

Wildcard tag blocking often doesn't save or work as expected.
Reliability issues: extension can be flaky, with missing tags or not appearing on the dash.
Privacy concerns: viewing other users' reading histories and limited logout options.
Setup/instructions are unclear or vague for new users.
Feature gaps: cannot block fandoms/characters and mobile support is lacking.

Recent reviews

This extension clashes with another ao3 usesrscipt that I use. Frankly the other one is way better then this one if I'm being honest. Thanks to this script when I use it always makes the other userscript crash, but somehow whenever I remove the userscript it works just fine. There must be an error in the code so I advised to think twice before using this extension. A note to the dev please correct the code or update it. If the crashes stop then I'll give it a higher rating until then I will give a one star.

this is the nth ao3 extension i've tried that just does not seem to actually work. all i want is a tag blocker, since they have no native means to do that and save it, but exactly zero extensions that claim to do that seem to do it either. starting to think ao3 must have changed something that precludes these sorts of extensions, bc it's insane that NONE of them seem to be working for me at all.

Is AO3 Enhancements 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 Enhancements requires very minimum permissions.

Risk impact analysis details

High Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk.
Low ******* ****** ** *** ********* ******** *******************

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