User Reviews

FB2 Reader is valued for letting you view FB2 files in Firefox with a lightweight, fast UI. Reviews emphasize it as one of the few FB2 readers available as a Firefox extension and note its usefulness even in beta, including local FB2.zip support. However, reliability dips after Firefox updates, with instances of the extension stopping or the icon graying out. Users also miss basic customization options (font/size/color) and report encoding problems with UTF-8 BOM. Overall, it’s handy but has notable stability and UX caveats.

Pros

Allows viewing FB2 files directly in Firefox (including local FB2.zip support)
Minimalist, distraction-free design with fast performance
Functional and useful even though in beta
One of the few Firefox extensions that enable FB2 reading
Particularly valued by Linux users as a readable FB2 option

Cons

Stops working or becomes unavailable after Firefox updates (reliability issue)
Lacks user customization options (no font, size, or color theme controls)
UTF-8 with BOM encoding issues reported by users requiring manual workarounds

Is FB2 Reader 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.

FB2 Reader requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

FB2 Reader is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
