Features & Capabilities

Peek is a browser extension that shows interactive previews for links to files and services directly on web pages. Just hover your mouse over a link to open a small popup with a live preview, powered by the browser’s built-in rendering and embedded viewers.

Peek supports a wide range of content—PDFs, Word/Excel/PowerPoint documents, images, videos, and audio—plus popular services like Google Docs Viewer and Microsoft Office Web Viewer. It’s privacy-minded and open-source on GitHub, with previews for many linked formats in lightweight, secure panels.

Is Peek: Preview PDFs, Office files, and more 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.

Peek: Preview PDFs, Office files, and more 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.

Peek: Preview PDFs, Office files, and more is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
