User Reviews

Reviews praise Library Extension as highly useful, fast, and powerful for finding and borrowing library items across Libby, CloudLibrary, Hoopla, and more. Key benefits include time and money savings, easy discovery, and strong multi-library support. A recurrent note is the desire for broader CloudLibrary integration to ensure uniform coverage across libraries.

Pros

Extremely useful; saves time and money by showing library holdings and enabling immediate access to e-books or audiobooks.
Simple and effective; easier to discover items than through many library apps or search tools.
Broad cross-library/platform coverage; supports Libby, CloudLibrary, Hoopla, and more across multiple sites.
Excellent for multi-library households; lets you choose which collections to search (physical and electronic) and see availability across libraries.
Well-supported and actively maintained; developers quickly add new libraries and fix issues.

Cons

CloudLibrary integration is inconsistent across libraries; users frequently request broader, more seamless CloudLibrary support.

Is Library Extension 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.

Library Extension 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.

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