Review summary

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
