User Reviews

Users praise AO3rdr for rating and marking fics, hiding unwanted content, and tracking read status (with device sync). Recurring negatives are Firefox compatibility issues and several nonfunctional bookmark/management features, suggesting maintenance problems that leave important features broken or inaccessible.

Pros

Easy to rate and mark fics (3‑point/star system) — many users rely on it to track reads.
Blocks/hides unwanted content (blacklist tags) so users can avoid spoilers or things they don’t want to see.
Shows read/unread status and integrates with bookmarks; sync across devices is possible once set up.

Cons

Compatibility and stability problems after Firefox updates — multiple users report features stop working on Firefox.
Bookmark/management features are incomplete or nonfunctional (bookmark-by-chapter, settings filters/search, blacklist page access).
Signs of poor maintenance/updates — users report broken behavior, limited support and difficulty getting features restored.

Recent reviews

Loved using this extension, was very useful in hiding the stuff I didn't want to see in Ao3. Unfortunately, I hit an issue in that it wasn't doing its job now that Firefox updated

Is AO3rdr 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.

AO3rdr requires a few sensitive permissions. Exercise caution before installing.
