Features & Capabilities

Geocache Viewer is a browser extension built for geocachers and puzzle solvers who want a smarter, cleaner way to view and analyze cache pages.

Open any Geocaching.com cache page and click the toolbar icon to instantly parse and reformat it into a distraction-free layout.

Features

Automatic extraction of cache details: name, owner, difficulty and terrain, size, and attributes.
Reveals decoded hints, embedded and background images, hidden HTML comments, and related links.
Highlights color-coded text and clues hidden within the short and long descriptions.
Detects and converts coordinates found anywhere on the page.
One-click handoff to Multidecoder and Text Manipulator for quick puzzle solving.
Import and export cache data as JSON to save or share your work.
Built-in tabs for FAQ, Advanced Options, and Bookmarklet setup.

Privacy

Geocache Viewer runs entirely in your browser. It does not collect, store, or transmit any data, and never touches your login or cookies. All processing happens locally and is never sent to external servers.

How to use

Open a Geocaching.com cache page you are signed in to.
Click the Geocache Viewer icon in your toolbar.
The page loads automatically in the viewer layout.

You can also paste a page's HTML manually, or use the bookmarklet (which also works on Android and iOS, where extensions are limited).

Is Geocache Viewer 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.

Geocache Viewer requires a few sensitive permissions. 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.

Geocache Viewer may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
